CD74HC374M96E4

Overview

The CD74HC374M96E4 is an octal D-type flip-flop manufactured by Texas Instruments within the high-speed CMOS logic family. It features eight independent positive-edge-triggered D-type flip-flops with tri-state outputs, housed in a 20-pin SOIC package. The device operates on a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 60 MHz. Propagation delay is specified at 165 ns at 2 V and 33 ns at 4.5 V under 50 pF load conditions. It functions reliably across an extended temperature range from -55 °C to +125 °C.

Feature Summary

• Octal configuration providing eight independent positive-edge-triggered D-type flip-flops for parallel data storage.
• Tri-state output capability allowing direct connection to bus structures without external buffer circuits.
• High-speed CMOS technology enabling operation up to 60 MHz with low static power consumption.

Applications

• Parallel-to-serial data conversion in communication interfaces
• Register banks for microprocessor memory addressing
• Buffering and latching operations in digital control systems

Procurement Notes

Verify that the ordering suffix E4 confirms compliance with RoHS standards and specifies the tape-and-reel packaging format. Confirm the manufacturer part number matches exactly to ensure the correct SOIC-20 physical dimensions and pinout are obtained for PCB layout compatibility.

Selection Notes

Select this component when an octal register with tri-state outputs is required for high-speed data handling. Ensure the system voltage falls within the 2 V to 6 V operating range and that the 60 MHz clock limit meets the application timing requirements.

Part Context

This part belongs to the CD74HC series of high-speed CMOS logic devices produced by Texas Instruments. It serves as a standard solution for storing eight bits of data in digital circuits, offering performance characteristics typical of the HC logic family while maintaining broad industrial temperature ratings.
