INTEGRATED CIRCUITS 74ALVT16952 2.5V/3.3V ALVT 16-bit registered transceiver (3-State) Product specification Supersedes data of 1995 Sep 19 IC23 Data Handbook 1998 Mar 19 Philips Semiconductors Philips Semiconductors Product specification 2.5V/3.3V 16-bit registered transceiver (3-State) 74ALVT16952 FEATURES * Two 8-bit registered transceivers * 5V I/O Compatible * 3-State buffers * Output capability: +64mA/-32mA * TTL input and output switching levels * Input and output interface capability to systems at 5V supply * Bus hold data inputs eliminate the need for external pull-up resistors to hold unused inputs DESCRIPTION The 74ALVT16952 is a high-performance BiCMOS product designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V. The 74ALVT16952 is a dual octal registered transceiver. Two 8-bit registers store data flowing in both directions between two bidirectional buses. Data applied to the inputs is entered and stored on the rising edge of the Clock (nCPXX) provided that the Clock Enable (nCEXX) is Low. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (nOEXX) is Low. Data flow from A inputs to B outputs is the same as for B inputs to A outputs. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level. * Live insertion/extraction permitted * Power-up 3-State * Power-up reset * No bus current loading when output is tied to 5V bus * Latch-up protection exceeds 500mA per JEDEC Std 17 * ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model QUICK REFERENCE DATA SYMBOL tPLH tPHL CIN CI/O ICCZ PARAMETER Propagation delay nCPBA to nAx or nCPAB to nBx Input capacitance I/O pin capacitance Total supply current CONDITIONS Tamb = 25C; GND = 0V CL = 50pF; VI = 0V or VCC VI/O = 0V or VCC Outputs disabled Outputs disabled TYPICAL 2.5V 3.0 3.0 3 9 40 3.3V 2.3 2.3 3 9 70 UNIT ns pF pF A ORDERING INFORMATION PACKAGES 56-Pin Plastic SSOP Type III 56-Pin Plastic TSSOP Type II TEMPERATURE RANGE -40C to +85C -40C to +85C OUTSIDE NORTH AMERICA 74ALVT16952 DL 74ALVT16952 DGG NORTH AMERICA AV16952 DL AV16952 DGG DWG NUMBER SOT371-1 SOT364-1 LOGIC SYMBOL (IEEE/IEC) 3 54 56 1 2 55 EN1 EN2 EN3 EN4 C5 C6 2, 3, 6 1, 4, 5 52 51 49 48 47 45 44 43 26 31 29 28 27 30 EN1 EN2 EN3 EN4 C5 C6 2, 3, 6 1, 4, 5 42 41 40 38 37 36 34 33 5 6 8 9 10 12 13 14 15 16 17 19 20 21 23 24 SH00069 1998 Mar 19 2 853-2053 19136 Philips Semiconductors Product specification 2.5V/3.3V 16-bit registered transceiver (3-State) 74ALVT16952 PIN CONFIGURATION 1OEAB 1CPAB 1CEAB GND 1A0 1A1 VCC 1A2 1A3 1A4 GND 1A5 1A6 1A7 2A0 2A1 2A2 GND 2A3 2A4 2A5 VCC 2A6 2A7 GND 2CEAB 2CPAB 2OEAB 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 1OEBA 1CPBA 1CEBA GND 1B0 1B1 VCC 1B2 1B3 1B4 GND 1B5 1B6 1B7 2B0 2B1 2B2 GND 2B3 2B4 LOGIC SYMBOL 5 6 8 9 10 12 13 14 1A0 1A1 1A2 1A3 1A4 1A5 1A6 1A7 2 3 55 54 1CPAB 1CEAB 1CPBA 1CEBA 1B0 1B1 1B2 1B3 1B4 1B5 1B6 1B7 1OEBA 1OEAB 56 1 52 51 49 48 47 45 44 43 15 16 17 19 20 21 23 24 2A0 2A1 2A2 2A3 2A4 2A5 2A6 2A7 27 26 30 2CPAB 2CEAB 2CPBA 2CEBA 2B0 2B1 2B2 2B3 2B4 2B5 2B6 2B7 2OEBA 2OEAB 29 28 2B5 VCC 2B6 2B7 GND 2CEBA 2CPBA 2OEBA 31 42 41 40 38 37 36 34 33 SH00071 SH00070 PIN DESCRIPTION PIN NUMBER 2, 55 27, 30 3, 54, 26, 31 5, 6, 8, 9, 10, 12, 13, 14, 15, 16, 17, 19, 20, 21, 23, 24 52, 51, 49, 48, 47, 45, 44, 43 42, 41, 40, 38, 37, 36, 34, 33 1, 56 28, 29 4, 11, 18, 25, 32, 39, 46, 53 7, 22, 35, 50 SYMBOL 1CPAB / 1CPBA 2CPAB / 2CPBA 1CEAB / 1CEBA 2CEAB / 2CEBA 1A0 - 1A7 2A0 - 2A7 1B0 - 1B7 2B0 - 2B7 1OEAB / 1OEBA 2OEAB / 2OEBA GND VCC NAME AND FUNCTION Clock input A to B / Clock input B to A Clock enable input A to B / Clock enable input B to A Data inputs/outputs (A side) Data inputs/outputs (B side) Output enable inputs Ground (0V) Positive supply voltage 1998 Mar 19 3 Philips Semiconductors Product specification 2.5V/3.3V 16-bit registered transceiver (3-State) 74ALVT16952 FUNCTION TABLE for Register nAx or nBx INPUTS nAx or nBx X L H nCPXX X nCEXX H L L INTERNAL Q NC L H OPERATING MODE Hold data Load data FUNCTION TABLE for Output Enable INPUTS nOEXX H L L INTERNAL Q X L H nAx or nBx OUTPUTS Z L H OPERATING MODE Disable outputs Enable outputs H = High voltage level L = Low voltage level = Low-to-High transition X = Don't care XX = AB or BA NC= No change H = High voltage level L = Low voltage level X = Don't care XX = AB or BA Z = High impedance "off" state LOGIC DIAGRAM nCEAB nCPAB nOEAB DETAIL A CE nA0 D CP Q Q CE D nB0 CP nA1 nA2 nA3 nA4 nA5 nA6 nA7 DETAIL A X 7 nB1 nB2 nB3 nB4 nB5 nB6 nB7 nCEBA nCPBA nOEBA SH00072 1998 Mar 19 4 Philips Semiconductors Product specification 2.5V/3.3V 16-bit registered transceiver (3-State) 74ALVT16952 ABSOLUTE MAXIMUM RATINGS1, 2 SYMBOL VCC IIK VI IOK VOUT IOUT Tstg PARAMETER DC supply voltage DC input diode current DC input voltage3 VO < 0 output in Off or High state output in Low state output in High state VI < 0 CONDITIONS RATING -0.5 to +4.6 -50 -0.5 to +7.0 -50 -0.5 to +7.0 128 -64 -65 to +150 UNIT V mA V mA V mA C DC output diode current DC output voltage3 DC output current Storage temperature range NOTES: 1.
