Product Overview: NXP PC74HC74T Dual D-Type Flip-Flop

The NXP PC74HC74T is a high-speed Si-gate CMOS device that is pin compatible with low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. This integrated circuit is part of the 74HC/HCT family and features two identical, independent dual D-type flip-flops with set and reset capabilities. Each flip-flop has independent data (D), set (SD), reset (RD), clock (CP) inputs, and outputs (Q and Q̅).

The PC74HC74T is designed for high-performance memory storing and data processing applications. The device can be used in a wide range of applications, from simple functions like flip-flops and registers to more complex computing elements. It is particularly well-suited for implementing buffer registers, shift registers, and control circuits due to its high noise immunity and low power consumption.
