PIN DESCRIPTION
SYMBOL ColumnRow Inputs PIN NO. 1-4 & 15-18 I/O I FUNCTION Keyboard inputs are designed for use with either a standard 4 x 5 keyboard or an inexpensive single contact (Form A) keyboard. Electronic input from a C can also be used. Valid key entry is defined by a connection between a single row and a single column. A built-in inverter provides oscillation with an inexpensive 3.579545 MHz crystal or ceramic resonator. The T/P MUTE is a conventional CMOS inverter output. It is low during pulse and tone mode dialing sequence and flash break; otherwise, it remains high. Pulling the mode pin to VSS place the dialer in tone mode. Pull to VDD or leave floating: Pulse mode (10 ppS, M/B = 2:3 or 1:2)

FUNCTION Hook switch input. Conventional CMOS input with an internal protection diode and a pull-high resistor to VDD. HKS = VDD: On-hook state. Chip in sleep mode, no operation. HKS = VSS: Off-hook state. Chip enabled for normal operation. During dialing, this input ignores HKS = VDD for durations of less than 150 mS (i.e., dialing is not terminated). Open drain dialing pulse output (Figure 1). Flash key causes DP /C5 to be active in both tone mode and pulse mode. During pulse dialing, maintains low state at all times. In tone mode, outputs a dual or single tone. Detailed timing diagram for tone mode is shown in Figure 2(a, b).

For example, if the redial content is 1 2 3 4 5 + A 3, it cannot be transferred to a memory location, and the content of Ln will not be modified.

1. The digits stored in Ln will be dialed out. 2. The type of output signal is determined by the mode switch. 3. The redial register content is the content of location number Ln. 4. If the content of Ln is 1, 2, 3, PT, 4, 5, 6, the redial function will execute the P/T function and the system will change to tone mode.
Access Pause
OFF HOOK , D1 , D2 , P , D3 , ..., Dn
1. The pause function can be stored in memory. 2. The pause function may be executed in normal dialing, redialing, or memory dialing (4.0 sec/pause). 3. The pause function can be stored as the first digit in memory. 4. The pause time depends on the number of times the P key is depressed. For example, if the sequence 1, 2, P, P, 4, 5, 6 is keyed in, then the pause time is 8 seconds. 5. The pause function timing diagram is shown in Figure 3.

Pulse-to-tone (PT)
1. OFF HOOK , D1 , D2 , ..., Dn , PT , D1' , D2' , ..., Dn' a. If the mode switch is set to pulse mode, then the output signal will be as follows: D1, D2, ..., Dn, no pause, D1', D2', ..., Dn' (Pulse) (Tone) In this case, the device can be reset to pulse mode only by going on-hook, because tone mode remains enabled after the digits have been dialed out. b. If the mode switch is set to tone mode, then the output signal will be as follows: D1, D2, ..., Dn, no pause, D1', D2', ..., Dn' (Tone) (Tone) c. The PT key may be pressed before the first sequence is dialed out completely. 2. OFF HOOK , R
If the mode switch is set to pulse mode, then the output signal will be as follows: D1, D2, ..., Dn, no pause, D1', D2', ..., Dn' (Pulse) (Tone) 3. OFF HOOK , A , Ln
a. The PT key can be stored in memory as a digit. The digits after the PT key are also sent in repertory dialing. b. The PT key does not stop dialing (no pause). c. The number stored in memory location Ln will be transferred to the redial register. d. The PT function timing diagram is shown in Figure 4.

key may be pressed before digits D1, D2, D3 are sent completely. Digits D4, D5, D6
may be pressed during the 100/300 mS. flash period. 2. The flash key cannot be stored as a digit in memory or in the redial register. 3. OFF HOOK Ln then , S , D1 , , D2 , D3 , , A, F , Ln D4 , D5 , D6 , A ,

D1, D2, D3, D4, D5, D6 will be dialed out. 4. The flash does not have first priority among the keyboard functions. 5. The flash pause time is 800 mS, so there is a pause of 800 mS between the flash and the next digit dialed (see Figure 5). 6. The dialer will not return to the initial state after the flash break time has elapsed. Publication Release Date: June 1996 Revision A3

Cascaded & Mixed Dialing
Cascaded Dialing 1. Definition of cascaded dialing: The next sequence may be pressed before the previous sequence is sent out completely. Examples of cascaded dialing. Example 1: Example 2: Example 3: Normal dialing I Repertory dialing 1 I Normal dialing I I I Repertory dialing 2 Repertory dialing 2 I... I... I...

Repertory dialing
2. The rectangles above represent one sequence of normal dialing, redialing, or repertory dialing. 3. At most 64 digits are allowed in cascaded dialing. There is no limitation on the number of sequences. 4. The content of cascaded dialing may include a combination of normal dialing, redialing, and repertory dialing. Redialing is valid only as the first key-in, however. 5. ON HOOK , OFF HOOK , R : The cascaded dialing sequences described in the above
examples will be dialed out only if they do not exceed a total of 32 digits. If the length of the combined sequences oversteps 32 digits then redialing is inhibited. Mixed Dialing 1. Definition of mixed dialing: Mixed dialing is a combination of sequences of normal dialing, repertory dialing, and redialing. The three examples given for cascaded dialing are also examples of mixed dialing, provided each sequence is dialed out completely before the next sequence is entered. 2. There is no limitation on the number of digits and sequences in mixed dialing. 3. If a mixed dialing sequence includes redialing, the redialing is valid only as the first key-in. 4. ON HOOK , OFF HOOK , R : The mixed dialing sequences described in the above
examples will be dialed out only if the total number of digits does not exceed 32. If the total oversteps 32 digits, then redialing is inhibited. Combination of Cascaded and Mixed Dialing 1. Cascaded dialing and mixed dialing can be combined; each follows the rules described above. 2. To apply redialing to combinations of cascaded and mixed dialing: ON HOOK , OFF HOOK , R : Redialing will be executed only if the total number of digits
does not exceed 32. If the total oversteps 32 digits, then redialing is inhibited. 3. If n cascaded sequences with a total of 60 digits have been dialed, then for the (n+1)th cascaded sequence, either one 4-digit normal dialing sequence or one complete repertory dialing sequence (length up to 32 digits) may be dialed. The (n+2)th sequence is not accepted for cascaded dialing. -8-

4. After a total of 64 digits of cascaded dialing, mixed dialing can be added.
