74AHCT594D-Q100,11

Shift Registers Overview

The Nexperia 74AHCT594D-Q100,11 is an automotive-qualified 8-bit serial-in, parallel-out shift register with an output register. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features Schmitt-trigger inputs for high noise immunity and overvoltage tolerance up to 5.5 V. It utilizes a 16-lead SO plastic small outline package (SOT109-1).

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards.
• Independent clocks and direct overriding clears for both shift and storage registers.
• Schmitt-trigger action on all inputs providing high noise immunity.
• Overvoltage tolerant inputs allowing operation in mixed-voltage environments.

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Selection Notes

Select this component when TTL-compatible logic levels are required in automotive systems. The AHCT variant ensures compatibility with Low-Power Schottky TTL while offering CMOS low power dissipation. Ensure the design accommodates the specified 4.5 V to 5.5 V supply range and the thermal characteristics of the SO16 package.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC/AHCT594-Q100 family of 8-bit shift registers with output registers. It shares functional similarities with other members like the 74AHC594D-Q100 but differs in input threshold specifications. The D-package variant provides a standard surface-mount solution suitable for general automotive electronics requiring robust data shifting capabilities.

Shift Registers Replacement Considerations

Direct pin-compatible substitutes include the 74AHC594D-Q100,118 and the 74HCT594D-Q100,118. Verify that the alternative's input logic levels match the system requirements, as the AHCT version specifically targets TTL compatibility.
