The 74VHC374TTR from STMicroelectronics is a high-speed CMOS device that belongs to a family of octal D-type flip-flops. This integrated circuit is designed to provide high-performance state storage in a wide array of digital systems. It features eight edge-triggered flip-flops with a common clock (CLK) and a common clear input (CLR).

Each flip-flop has its own independent D-type input for data and Q output for the stored data. The 74VHC374TTR is particularly well-suited for applications that require the capture and storage of multiple data lines simultaneously, such as data buses in computers, communication systems, and other digital equipment.

The device operates on a 2V to 5.5V power supply range, making it compatible with a variety of logic families and allowing it to be used in both 3.3V and 5V systems. The low power consumption and high noise immunity of CMOS technology, combined with the speed of LSTTL, make this device an excellent choice for high-speed, low-power applications.

The 74VHC374TTR is packaged in a TSSOP20 (thin shrink small outline package) that is surface-mountable, providing a compact footprint for densely packed PCBs. This package is designed for optimal thermal and electrical performance, ensuring reliability and functionality in a wide range of environmental conditions.

Key features of the 74VHC374TTR include:
