74AHCT594DB-Q100J

Shift Registers Overview

The Nexperia 74AHCT594DB-Q100J is an automotive-grade, high-speed Si-gate CMOS 8-bit shift register with output register. It operates within a supply voltage range of 2.0 V to 5.5 V and features TTL-compatible input levels. The device includes separate clocks for the shift and storage registers, along with direct overriding clears. It is housed in a SO16 plastic small outline package (SOT109-1) and is specified for ambient temperatures from -40 °C to +125 °C.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL-level inputs compatible with Low-Power Schottky TTL (LSTTL)
• Independent positive-edge triggered clocks for shift and storage registers
• Direct overriding clear inputs for both shift and storage stages

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix 'J' against the manufacturer's current documentation to confirm exact packaging or marking variations. Confirm that the SO16 package designation matches the required footprint for the target PCB design. Ensure the component meets the specific temperature grade requirements for the intended automotive application environment.

Shift Registers Selection Notes

Select this component when TTL logic compatibility is required alongside high-speed CMOS performance. The AHCT series is appropriate for systems interfacing with legacy LSTTL devices. Verify that the operating voltage aligns with the 4.5 V to 5.5 V range for optimal TTL threshold compliance. Consider the SO16 package dimensions if space constraints differ from other available options like TSSOP or DHVQFN.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC(AHCT)594-Q100 family of 8-bit shift registers with output registers. The family provides pin-compatible variants across different logic families (AHC and AHCT) and package types including SO16, TSSOP16, and DHVQFN16. All variants share the same functional architecture but differ in input voltage thresholds and physical housing.

Shift Registers Replacement Considerations

Other members of the 74AHC(AHCT)594-Q100 family may serve as replacements if package differences are acceptable. Variants such as 74AHCT594PW-Q100 or 74AHCT594BQ-Q100 offer identical functionality in TSSOP16 or DHVQFN16 packages respectively.
