74AHCT164PW,112

Shift Registers Overview

The Nexperia 74AHCT164PW,112 is an 8-bit serial-in/parallel-out shift register housed in a TSSOP14 package (SOT402-1). 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 two serial data inputs (DSA, DSB) and eight parallel outputs (Q0-Q7), shifting data on LOW-to-HIGH clock transitions. Key electrical parameters include a maximum propagation delay of 13.5 ns at 50 pF load, a maximum input leakage current of 2.0 μA, and a maximum supply current of 80 μA.

Shift Registers Feature Summary

• Accepts TTL logic levels for input signals
• Provides overvoltage tolerant inputs up to 5.5 V
• Includes Schmitt-trigger action on all inputs
• Features an active LOW master reset input

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Parallel output expansion for microcontrollers
• Mixed voltage environment signal translation

Shift Registers Procurement Notes

Verify the specific ordering suffix ',112' corresponds to the standard tube packaging configuration defined in the official datasheet. Confirm that the component meets RoHS compliance standards as specified by Nexperia. Ensure the selected package variant matches the required PCB footprint dimensions for the TSSOP14 outline.

Shift Registers Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS performance characteristics. The 74AHCT series is appropriate for systems interfacing with legacy TTL logic sources. Verify that the operating voltage remains strictly within the 4.5 V to 5.5 V range to ensure correct logic level interpretation and timing specifications.

Shift Registers Part Context

This part belongs to the 74AHCT164 family of 8-bit shift registers manufactured by Nexperia. It shares functional compatibility with the 74AHC164 but utilizes HCT input levels. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package, designed for surface-mount assembly with a body width of 4.4 mm.
