74HC597PW-Q100J

Overview

The Nexperia 74HC597PW-Q100J is an automotive-grade 8-bit shift register with input flip-flops, housed in a TSSOP16 package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and clamp diodes on inputs for interfacing with voltages exceeding VCC. It complies with AEC-Q100 Grade 1 standards.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Includes direct load and clear functions for the shift register
• Features input clamp diodes for extended voltage interfacing
• Provides latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Automotive electronic systems requiring robust logic control
• Mixed voltage environments utilizing current limiting resistors
• Applications necessitating parallel-to-serial data conversion

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature grade. Ensure compatibility with AEC-Q100 requirements for your target application. Confirm that the TSSOP16 footprint matches your PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when an 8-bit storage register feeding a serial-out shift register is required. It is suitable for designs needing positive edge-triggered clocks for both registers. Consider its wide supply voltage range and high noise immunity for reliable operation in electrically noisy automotive or industrial environments.

Part Context

This part belongs to the 74HC597-Q100 family of 8-bit shift registers with input flip-flops. It shares functional similarities with other members of the series but is distinguished by its specific TSSOP16 packaging and automotive qualification. The device integrates both a storage register and a shift register with independent clocking capabilities.
