74AHC594D,112

Shift Registers Overview

The Nexperia 74AHC594D,112 is an 8-bit serial-in, parallel-out shift register with a storage register. It operates within a supply voltage range of 2.0 V to 5.5 V and features balanced propagation delays. The device includes independent clocks for the shift and storage registers, as well as direct overriding clears. It provides overvoltage tolerant inputs up to 5.5 V and high noise immunity. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). It is specified from -40 °C to +125 °C.

Shift Registers Feature Summary

• 8-bit non-inverting serial-in, parallel-out shift register feeding an 8-bit D-type storage register
• Independent positive-edge triggered clocks and direct overriding clears for both shift and storage registers
• Overvoltage tolerant inputs allowing interface to voltages in excess of VCC
• High noise immunity with Schmitt-trigger action at all inputs

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. Ensure compatibility with JEDEC standards and check for any recent Product Change Notifications regarding assembly or labeling updates before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with separate storage output is required. It supports CMOS input levels and offers wide supply voltage flexibility. Consider the SO16 package dimensions and thermal characteristics for PCB layout. Verify that the operating temperature range meets system requirements.

Shift Registers Part Context

This part belongs to the 74AHC series of high-speed Si-gate CMOS logic devices. It is pin-compatible with Low-Power Schottky TTL (LSTTL). The 74AHC594D variant specifically utilizes the SO16 plastic small outline package. It is designed for applications requiring reliable data shifting and storage with low power dissipation.

Shift Registers Replacement Considerations

Check for equivalent parts such as the 74AHCT594D if TTL input levels are needed instead of CMOS. Verify pinout compatibility and electrical specifications like propagation delay and supply voltage range before substituting.
