Overview
The MC74HC574ADWG, produced by onsemi, is an Octal 3-State Noninverting D Flip-Flop integrated circuit. This device is part of the high-performance silicon-gate CMOS family and is designed to provide reliable and efficient data storage and transfer. It is identical in pinout to the LS574 and offers compatibility with standard CMOS outputs, as well as LSTTL outputs when used with pull-up resistors. The MC74HCT574A variant can also serve as a level converter for interfacing TTL or NMOS outputs to high-speed CMOS inputs.
