74AHC595PW/AUJ

Shift Registers Overview

The NXP USA Inc. 74AHC595PW/AUJ is an 8-bit serial-in/serial-out or parallel-out shift register with output latches, manufactured by Nexperia under the NXP brand. It features a storage register and 3-state outputs. The device operates on a wide supply voltage range from 2.0 V to 5.5 V. It includes separate clocks for the shift and storage registers, a serial input (DS), and a serial output (Q7S) for cascading. An asynchronous reset (MR) input clears the shift register. The component utilizes Schmitt-trigger inputs for high noise immunity and overvoltage tolerant inputs up to 5.5 V.

Shift Registers Feature Summary

• Features balanced propagation delays and CMOS low power dissipation.
• Includes Schmitt-trigger action on all inputs for enhanced noise immunity.
• Provides overvoltage tolerant inputs allowing use as translators in mixed voltage environments.
• Offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature range. Confirm RoHS compliance status and ensure the supplier provides valid traceability documents. Cross-reference the manufacturer part number with authorized distributor databases to validate authenticity before procurement.

Shift Registers Selection Notes

Select this component when designing systems requiring 8-bit serial-to-parallel conversion with independent storage latching. Ensure the operating voltage aligns with the 2.0 V to 5.5 V range. Consider the TSSOP16 package dimensions for PCB layout constraints. Verify that the logic family matches the system's input requirements for proper signal interfacing.

Shift Registers Part Context

This component belongs to the 74AHC and 74AHCT logic families, which are standard CMOS shift registers. The 74AHC series offers high-speed operation with CMOS input levels, while the 74AHCT variant provides TTL-compatible inputs. Both variants share similar functional characteristics but differ in input threshold specifications for compatibility with different logic standards.

Shift Registers Replacement Considerations

Check for direct equivalents such as the 74AHCT595PW for TTL input compatibility. Verify pinout and electrical specifications against alternative manufacturers' datasheets to ensure functional interchangeability without circuit redesign.
