CD74HC597EE4

Shift Registers Overview

The CD74HC597EE4 is a high-speed silicon gate CMOS device from the CD74HC597 family, manufactured by Texas Instruments. It integrates an 8-bit parallel-in/serial-in, serial-out shift register and an 8-flip-flop input storage register. The component operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -55°C to +125°C. It utilizes a 16-pin PDIP package.

Shift Registers Feature Summary

• Features buffered inputs with asynchronous parallel load capability for direct data transfer into the shift register.
• Provides balanced propagation delay and transition times while maintaining significant power reduction compared to LSTTL logic families.
• Includes a master reset function that clears the shift register asynchronously when activated.

Shift Registers Applications

• Data acquisition systems requiring temporary storage before processing
• Industrial control applications involving serial-to-parallel data conversion
• Communication interfaces utilizing shift register architectures

Shift Registers Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free packaging and RoHS compliance as indicated in official documentation. Confirm the active production status and availability through authorized distributors. Ensure the selected package matches the required PCB footprint specifications.

Shift Registers Selection Notes

Select this component for designs requiring robust noise immunity and compatibility with standard TTL loads. The HC series offers a wider voltage operating range than HCT variants. Consider the PDIP package for through-hole mounting requirements or prototyping environments where surface mount options are not preferred.

Shift Registers Part Context

This part belongs to the Texas Instruments CD74HC597 family of high-speed CMOS logic devices. It serves as a pin-compatible replacement for legacy LSTTL 597 devices, offering improved performance characteristics.
