M74HC294 Datasheet (ST Microelectronics) - PROGRAMMABLE DIVIDER/TIMER

M74HC294, PROGRAMMABLE DIVIDER/TIMER

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

They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

These devices are programmable frequency dividers.
