PIN DESCRIPTION TABLE
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 guaran-
teed. 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.

FUNCTIONAL DESCRIPTION

APPLICATION INFORMATION
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.
