74AHCT595PW,112

Shift Registers Overview

The Nexperia 74AHCT595PW,112 is an 8-bit serial-in/serial or parallel-out shift register with output latches and 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL compatible inputs. The device includes separate clocks for the shift and storage registers, a serial input (DS), a serial output (Q7S) for cascading, and an asynchronous master reset (MR). It is housed in a TSSOP16 package.

Shift Registers Feature Summary

• Features TTL compatible inputs for direct interfacing with standard logic families.
• Includes Schmitt-trigger action on all inputs to ensure tolerance of slower rise and fall times.
• Provides overvoltage tolerant inputs up to 5.5 V, enabling use as translators in mixed voltage environments.

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix '112' against official Nexperia documentation to confirm tape and reel packaging specifications. Ensure the component matches the TSSOP16 package outline SOT403-1. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding assembly or material updates before finalizing procurement.

Shift Registers Selection Notes

Select this component when TTL logic levels are required at the input stage while maintaining CMOS performance characteristics. The 74AHCT595 variant is specifically designed for 5 V systems. Verify that the operating temperature range of -40 °C to +125 °C meets the environmental requirements of the target application design.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC/AHCT595 family of 8-bit shift registers. It shares functional similarities with the 74AHC595 but differs in input logic compatibility. The PW suffix indicates the TSSOP16 plastic thin shrink small outline package. This series is widely used in digital electronics for expanding I/O capabilities.

Shift Registers Replacement Considerations

Direct pin-compatible replacements include other manufacturers' 74AHCT595 variants. Verify electrical parameters such as propagation delay and supply current limits match the original design constraints before substitution.

Shift Registers FAQ

How does the 74AHCT595 handle mixed voltage environments?

The inputs are overvoltage tolerant up to 5.5 V, allowing the device to interface safely with higher voltage signals even if powered by lower voltages within its specified range.

What is the function of the MR input?

The MR (Master Reset) input is active LOW and asynchronously resets the shift register stages without affecting the storage register state.
