CD74HCT164M

Shift Registers Overview

The CD74HCT164M is an 8-bit serial-in, parallel-out shift register manufactured by Harris Corporation. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes HCT CMOS logic technology. The device is housed in a 14-pin SOIC package and supports a propagation delay of 36 ns. It functions with a positive edge trigger and includes asynchronous reset capabilities. The component is rated for operation between -55 °C and +125 °C.

Shift Registers Feature Summary

• Converts serial data input into parallel output across eight bits
• Utilizes HCT CMOS logic for compatibility with standard TTL interfaces
• Features asynchronous clear function for immediate state reset

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• General-purpose shift register applications
• Digital signal processing interfaces

Shift Registers Procurement Notes

Verify the manufacturer designation on the datasheet, as this part number is historically associated with Harris Corporation but may also be produced by Texas Instruments under similar nomenclature. Confirm the specific suffix requirements for packaging variations such as cut tape or reel formats against current distributor specifications. Ensure the RoHS compliance status matches project requirements, as older Harris-produced units may differ from modern equivalents.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is required within the HCT logic family. It is suitable for designs needing a wide operating temperature range up to 125 °C. Consider the 14-pin SOIC package constraints for PCB layout. Verify that the 4.5 V to 5.5 V supply voltage aligns with the system power rails before finalizing the design.

Shift Registers Part Context

This component belongs to the 74HCT series of high-speed CMOS logic devices. Originally developed by Harris Semiconductor, these parts were widely adopted before Harris's semiconductor division was acquired by Intersil, which later merged with Renesas Electronics. Texas Instruments also manufactures equivalent parts in the CD74HCT series, maintaining functional compatibility within the industry standard.
