概要

Description

The SN74HC574PWR is an octal (8-bit) D-type flip-flop designed for high-speed operation in digital circuits. It features a transparent latch that captures input data on the rising edge of the clock signal, allowing for the storage and retrieval of binary information. The "HC" in its name indicates that it operates at high speed with low power consumption, compatible with standard TTL logic levels.
The device has two sets of eight D inputs and outputs, with an asynchronous reset feature that can clear all outputs to a low state. It operates with a supply voltage of 2V to 6V and is suitable for various applications, including data storage, register files, and temporary data holding in digital systems.
The SN74HC574PWR is available in a TSSOP (Thin Shrink Small Outline Package) form factor, making it suitable for space-constrained designs. Its reliability and versatility make it a popular choice in both consumer electronics and industrial applications.
