CD74HC173M

Overview

The CD74HC173M is a high-speed CMOS quad D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to +125 °C. The device features a propagation delay of 200 ns, with output drive capabilities of -7.8 mA for high level and 7.8 mA for low level. It is housed in a 16-pin SOIC package.

Feature Summary

• Contains four independent D-type flip-flops with single-ended inputs.
• Outputs are controlled by a three-state control input for bus driving applications.
• Compatible with standard CMOS logic families for system integration.

Applications

• Parallel data storage registers
• Shift register configurations
• Bus-oriented memory systems

Procurement Notes

Verify the specific suffix 'M' indicates the SOIC-16 package variant rather than the tape-and-reel 'PW' or 'PWR' versions. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the supplier provides valid traceability for the component lot.

Selection Notes

Select this component when a quad D-latch with tri-state capability is required for parallel data retention. The HC series offers higher speed compared to legacy 74HCT variants while maintaining CMOS power efficiency. Verify that the 2V minimum supply voltage aligns with the target system's power architecture.

Part Context

This part belongs to the Texas Instruments CD74HC173 family of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic circuits requiring multiple synchronized data storage elements within a single integrated circuit package.
