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. The types.
