M74HC7294 Datasheet PDF - STMicroelectronics

DESCRIPTION
The M74HC7294 is an high speed CMOS PROGRAMMABLE DIVIDER/TIMER fabricated with silicon gate C2MOS technology.
This device is a programmable frequency divider and have two clock inputs, either one may be used for clock gating. (see the function table).
The M74HC7294 can divide from 22 to 215. This device feature an active-low clear input to initialize the state of all flip-flops. To facilitate incoming inspection, test points (TP) are provided. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
This device have all outputs "Totem Pole"
