Description
The 74HCT574PW,118 is a high-speed, silicon-gate CMOS Octal D-type Flip-Flop featuring 3-state outputs. This device is designed for bus-oriented applications where data storage and controlled signal transmission are required. It contains eight D-type flip-flops with a common clock input and a common output enable (OE) control.
Data at the D inputs is transferred to the Q outputs on the positive-going transition of the clock (CP) input. The 3-state outputs provide a high-impedance state, allowing for efficient bus isolation and preventing signal contention in multi-master systems. The HCT designation indicates that the inputs are TTL-compatible, allowing for easy integration with legacy TTL-based logic circuits while retaining the low power benefits of CMOS technology.
