DESCRIPTION

The 54/74HC292/7292 and HC294/7294 are high
speedCMOS PROGRAMMABLEDIVIDER/TIMER
fabricated with silicon C2MOStechnology.

They achieve the high speed operation similar to
equivalent LSTTL while maintaining the CMOSlow
power dissipation.

These devices are programmable frequency
dividers. Thetypeshavetwoclockinputs,eitherone
may be used for clock gating. (see the function
table). The HC292/7292 can divide from 22to 231,
and theHC294/7294 can divide from22to215. 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”
outputconfiguration.

HC7292/7294 have all outputs ”Totem Pole”.
