74HC597D-Q100J

Overview

The 74HC597D-Q100J is an automotive-grade 8-bit shift register with input flip-flops, manufactured by Nexperia. It features a storage register feeding a parallel-in, serial-out shift register, both utilizing positive edge-triggered clocks. The device includes direct load and clear inputs, along with clamp diodes for over-voltage interfacing. Qualified to AEC-Q100 Grade 1 standards, 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. It is housed in a 16-lead SO plastic small outline package (SOT109-1).

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• High noise immunity and CMOS low power dissipation
• Input levels compliant with CMOS standards
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Applications

• Automotive electronic systems requiring robust data shifting
• Parallel-to-serial data conversion circuits
• Industrial control applications operating in extended temperature ranges

Procurement Notes

Verify the specific ordering suffix and package variant against the official Nexperia datasheet before procurement. Confirm that the component meets the required AEC-Q100 Grade 1 qualification for your target application. Ensure compatibility with the specified supply voltage and temperature range constraints defined in the recommended operating conditions.

Selection Notes

Select this component when an 8-bit shift register with input latching is required for automotive or industrial environments. The HC logic family provides CMOS-level input compatibility and wide supply voltage flexibility. Consider the SO16 package dimensions and thermal derating characteristics if high power dissipation is anticipated in the design.

Part Context

This part belongs to the 74HC597-Q100 series, which includes variants like the 74HCT597D-Q100J. The 'D' indicates the SO16 package type, while 'Q100' signifies automotive qualification. The 'J' suffix typically denotes specific tape and reel packaging details as defined by the manufacturer's ordering information.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified 8-bit shift registers from compatible manufacturers. Verify pinout compatibility and electrical specifications such as propagation delay and supply voltage ranges before substitution.
