HI-8105 & HI-8106
January 2001
DESCRIPTION
The HI-8105 & HI-8106 are silicon gate CMOS devices designed for 'glue' logic applications. They are simple 16 stage dividers with programmable division. The HI-8105 has a one pin oscillator while the HI-8106 receives a clock input. The one pin oscillator frequency is set by a resistor to VDD and the capacitance to AC ground at the pin. The wafer processing enables operation to 1 volt guaranteed. The chip is designed for low power performance. As a result the maximum output frequency is 5 MHz while the internal logic will run considerably higher. A companion version, HI-8107, features a crystal oscillator circuit and a 8 stage programmable divider.

HI-8105 & HI-8106
FUNCTIONAL DESCRIPTION
The HI8105 and HI-8106 are 16 stage serial counters. Each stage's Q is input to a 1 of 16 decoder. A 4 bit code at pins 4 through 7 selects which stage is routed to the output at pin 3. The counter clocks on the negative transition of pin 8. Figure 1 shows the oscillator circuit of the HI-8105. The charging time is controlled by a delay circuit and the hystersis window. The window is typically 0.6V wide at VDD=5.0V. Figure 2 shows the bonding option which omits the N device pulldown and thereby allows the simple clock input of the HI-8106.
