Product Description

The PC74HC374T octal D-type flip-flop incorporates 8 edge-triggered, D-type flip-flops with 3-state outputs in a 20-pin TSSOP package. Each flip-flop features a separate direct clear input (CLR) and clock input (CP) which triggers on the rising edge. When the clear input is held low, it overrides the clock and data inputs, forcing the Q output low. The 3-state output configuration allows for the connection of multiple outputs to a common bus, controlled via the output enable (OE) input.

This device is fabricated using NXP's advanced silicon-gate CMOS technology, providing a robust and high-performance solution for digital circuit design. With its broad VCC operating range and high noise immunity, the PC74HC374T is an excellent choice for interfacing with different logic levels and for use in mixed-voltage environments.

For designers and engineers looking for a reliable flip-flop solution, the NXP PC74HC374T offers a combination of performance, power efficiency, and versatility, making it a go-to component for digital logic circuits.
