CD74HC597M

Shift Registers Overview

The CD74HC597M is an 8-bit shift register with input storage manufactured by Harris Corporation. It operates within a supply voltage range of 2V to 6V and features a propagation delay of 350ns at nominal supply. The device supports serial-in parallel-out (SIPO) operation and is housed in a 16-pin PDSO package. It functions as a high-speed CMOS logic circuit designed for data storage and transfer applications.

Shift Registers Feature Summary

• High-speed CMOS technology for efficient logic operations
• Integrated input storage registers for data stability
• Supports serial-to-parallel data conversion

Shift Registers Applications

• Data acquisition systems requiring serial input buffering
• Parallel output expansion in microcontroller interfaces
• Digital signal processing data path storage

Shift Registers Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments acquired Harris Semiconductor's logic product line. Ensure the specific part number matches the legacy Harris designation or the corresponding TI equivalent if sourcing from current distributors. Confirm RoHS compliance status as original Harris parts may predate modern environmental regulations.

Shift Registers Selection Notes

Select this component when a reliable 8-bit serial-to-parallel converter with input latching is required. The 2V to 6V operating range offers flexibility for various logic families. Consider the 350ns propagation delay for timing constraints in your system design. Verify package availability in 16-pin SOIC formats compatible with surface mount assembly processes.

Shift Registers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. Originally produced by Harris Corporation before its semiconductor division was acquired by Texas Instruments, it represents a standard industrial-grade logic solution. The device provides robust performance for general-purpose digital logic applications requiring data storage capabilities.

Shift Registers Replacement Considerations

Texas Instruments CD74HC597M serves as the direct successor following the Harris Semiconductor acquisition. Other manufacturers such as onsemi offer functional equivalents like the MC74HC597ADR2G. Verify pin compatibility and electrical specifications before substituting with third-party alternatives.
