To facilitate incoming PROGRAMMABLE DIVIDER/TIMER fabricated inspection, test points (TP) are provided. All with silicon gate C2MOS technology. inputs are equipped with protection circuits This device is a programmable frequency divider against static discharge and transient excess and has two clock inputs, either one may be used voltage. for clock gating. (see the function table). This device has Q output with "Totem Pole" The M74HC294 can divide from 22 to 215. This configuration and test point TP with "Open Drain" device feature an active-low clear input to initialize output configuration. PIN CONNECTION AND IEC LOGIC SYMBOLS August 2001 1/11 M74HC294
