M74HC294 General Description

The M74HC294 is an high speed CMOS PROGRAMMABLE DIVIDER/TIMER fabricated with silicon gate C²MOS technology.

This device is a programmable frequency divider and has two clock inputs, either one may be used for clock gating. (see the function table).

The M74HC294 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 has Q output with "Totem Pole" configuration and test point TP with "Open Drain" output configuration.
