M74ACT574B Datasheet OCTAL D-TYPE FLIP FLOP WITH 3 STATE OUTPUT NON INVERTING

Manufacturer: STMicroelectronics

General Description

The ACT574 is an advanced high-speed CMOS OCTAL D-TYPE FLIP FLOP with 3 STATE OUTPUT NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

These 8 bit D-Type flip-flops are controlled by a clock input (CK) and an output enable input (OE).

On the positive transition of the clock, the Q outputs will be set to logic state that were setup at the D inputs.
