DESCRIPTION  
The 54/74HC292/7292 and HC294/7294 are high  
speed CMOS PROGRAMMABLE DIVIDER/TIMER  
fabricated with silicon C2MOS technology.  
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.  
They achieve the high speed operation similar to  
equivalent LSTTL while maintaining the CMOS low  
power dissipation.  
These devices are programmable frequency  
dividers. The typeshave two clockinputs, 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  
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 isdefined 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 followingequation. ICC(opr) = CPD • VCC • fIN + ICC
