CD74HCT175EG4

Overview

The CD74HCT175EG4 is a quad D-type flip-flop from Texas Instruments' 74HCT logic family, housed in a 16-pin DIP package. It operates on a single 4.5V to 5.5V supply and features four independent D-type flip-flops with positive-edge triggering. The device includes an asynchronous master reset input that clears all outputs when active. Designed for through-hole mounting, it supports clock frequencies up to 25 MHz and functions reliably within an industrial temperature range of -55°C to 125°C.

Feature Summary

• Contains four independent D-type flip-flops with complementary outputs
• Positive-edge triggered data capture synchronized to the clock signal
• Asynchronous master reset input forces all Q outputs to a low state
• Compatible with standard 5V CMOS and LSTTL logic families

Applications

• Parallel-to-serial data conversion circuits
• General-purpose digital storage registers
• Shift register configurations for data processing
• Timing control and synchronization logic systems

Procurement Notes

Verify the specific EG4 suffix indicates the lead-free, RoHS-compliant variant of the standard CD74HCT175E. Confirm the manufacturer's component status, as production schedules may vary. Ensure the procurement channel provides official traceability documentation to guarantee authenticity and compliance with environmental regulations required for modern electronic assemblies.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or legacy board designs. It serves as a direct replacement for the non-green CD74HCT175E in applications needing robust noise immunity and LSTTL compatibility. Consider surface-mount alternatives like the M96 variant if space constraints dictate SMD packaging for high-volume manufacturing.

Part Context

This part belongs to the Texas Instruments 74HCT series, which bridges the performance gap between standard CMOS and Low-power Schottky TTL. The HCT series maintains the low power consumption of CMOS while offering switching speeds comparable to LSTTL. The CD74 prefix denotes commercial grade temperature ratings and standard plastic packaging suitable for general-purpose computing and industrial control applications.
