DESCRIPTION
The 54/74HC292/7292 and HC294/7294 are high
speed CMOS PROGRAMMABLE DIVIDER/TIMER
fabricated with silicon C2MOS technology.
They achieve the high speed operation similar to
equivalent LSTTL while maintaining the CMOS low
power dissipation.
These devices are programmable frequency
dividers. The types have two clock inputs, either one
may be used for clock gating. (see the function
table). The HC292/7292 can divide from 22 to 231,
and the HC294/7294 can divide from 22 to 215. The
types feature an active-low clear input to initialize
the state of all flip-flops. To facilitate incoming
inspection, test points are provided. (TP1, TP2 and
TP3 on the HC292/7292 and TP on the
HC294/7294). All inputs are equipped with
protection circuits against static discharge and
transient excess voltage.
HC292/294 have Q output with ”Totem pole”
configuration and test point TP with ”Open Drain”
output configuration.
HC7292/7294 have all outputs ”Totem Pole”.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC
