HI-8105 Datasheet, PDF (1/5 Pages) Holt Integrated Circuits – PROGRAMMABLE DIVIDER WITH OSC OR CLK

January 2001
HI-8105 & HI-8106
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 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.
