Description

  The 54/74HC292/7292 and HC294/7294 are high speedCMOS PROGRAMMABLE DIVIDER/TIMER fabricated with silicon C2MOS technology.

 54/74HC292/7292 and HC294/7294 achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

  These devices 54/74HC292/7292 and HC294/7294 are programmable frequency dividers. The typeshave 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".
