74HCT597D-Q100J

Shift Registers Overview

The Nexperia 74HCT597D-Q100J is an automotive-qualified, 8-bit shift register with input flip-flops. It comprises a parallel-in, serial-out shift register and an 8-bit storage register, both utilizing positive edge-triggered clocks. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. It features TTL-compatible input levels, asynchronous master reset, direct load capabilities, and clamp diodes for interface protection.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1) standards
• Dual-clock architecture with separate shift and storage registers
• TTL-level compatible inputs for HCT logic family integration
• Asynchronous master reset and direct parallel load functionality

Shift Registers Applications

• Automotive electronic systems requiring robust data shifting
• Industrial control applications operating at elevated temperatures
• Parallel-to-serial data conversion circuits
• Serial-to-parallel output expansion modules

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature grade. Confirm that the procurement channel provides valid traceability for AEC-Q100 qualified components. Cross-reference the part number with the latest product status information to confirm production availability and obsolescence status before finalizing orders.

Shift Registers Selection Notes

Select this component when designing systems requiring simultaneous parallel loading and serial shifting within an automotive environment. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range typical of the HCT logic family. Verify that the SOIC-16 package dimensions align with the PCB layout constraints and thermal management requirements for the intended operating temperature range up to 125 °C.

Shift Registers Part Context

This device belongs to the Nexperia 74HC_HCT597_Q100 series, which includes variants optimized for different logic families. While the HC variant supports a wider voltage range, the HCT version specifically targets TTL compatibility. All members of this series share the same functional architecture and are designed to meet rigorous automotive reliability standards.

Shift Registers Replacement Considerations

Direct substitutes include the 74HC597D-Q100J for CMOS-level applications or other 74HCT597 variants from Nexperia with identical pinouts. Verify that any replacement maintains the required AEC-Q100 Grade 1 qualification and matches the SOIC-16 package specifications.
