74AHC595D,112

Shift Registers Overview

The Nexperia 74AHC595D,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 2.0 V to 5.5 V. The device features separate clocks for the shift and storage registers, a serial input (DS), and a serial output (Q7S) for cascading. It includes an asynchronous master reset (MR) input that resets the shift register on a LOW signal. Data shifts on the LOW-to-HIGH transition of the SHCP input and transfers to the storage register on the STCP input. Outputs are enabled when OE is LOW.

Shift Registers Feature Summary

• Features Schmitt-trigger action on all inputs for high noise immunity
• Includes overvoltage tolerant inputs capable of handling up to 5.5 V
• Provides balanced propagation delays across operating conditions
• Offers ESD protection exceeding 2000 V per HBM and 1000 V per CDM standards

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix '112' against current Nexperia documentation to confirm package type and reel specifications. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the selected variant matches the required temperature range and package dimensions for your PCB layout before finalizing procurement orders.

Shift Registers Selection Notes

Select this component for designs requiring CMOS logic levels and wide voltage operation between 2.0 V and 5.5 V. Choose the SO16 package for standard surface-mount assembly needs. Consider the 74AHCT595 variant if TTL-compatible input levels are required instead of CMOS levels. Verify thermal dissipation requirements for the SO16 package under maximum load conditions.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC/AHCT595 family of 8-bit shift registers. It is manufactured in an SO16 plastic small outline package (SOT109-1). The device is specified for ambient temperatures ranging from -40 °C to +125 °C. It utilizes CMOS technology for low power dissipation while maintaining high noise immunity suitable for industrial applications.

Shift Registers Replacement Considerations

The 74AHC595D,118 is a documented substitute offering identical functionality in the same SO16 package. Verify pin compatibility and electrical characteristics before substitution.
