CD40174BM

Overview

The CD40174BM is a CMOS hex D-type flip-flop manufactured by Texas Instruments. It features six independent D-type flip-flops with positive-edge triggering and a master reset input. The device operates within a supply voltage range of 3V to 18V and supports clock frequencies up to 16 MHz. It utilizes a 16-SOIC surface-mount package and functions across an extended temperature range from -55°C to +125°C.

Feature Summary

• Contains six independent D-type flip-flops with positive-edge triggering
• Includes a dedicated master reset input for synchronous clearing
• Supports wide operating supply voltage ranges typical of CMOS logic

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations in digital systems
• Frequency division and counting applications

Procurement Notes

Verify the specific suffix '96' or standard designation against the manufacturer's current production status, as suffixes often indicate packaging variations such as tape and reel quantities rather than functional changes. Confirm RoHS compliance and lead times directly with authorized distributors to ensure alignment with project requirements.

Selection Notes

Select this component when a compact solution for storing six bits of data is required using surface-mount technology. Ensure the design accommodates the specified 16-SOIC footprint and that the system power supply remains within the 3V to 18V operational limits defined for the 4000B series.

Part Context

This part belongs to the Texas Instruments CD4000B series of CMOS logic devices. The CD40174 variant specifically provides hex D-type flip-flops, distinguishing it from other series members like counters or inverters. It serves as a fundamental building block for sequential logic circuits requiring reliable state retention.
