74AHCT594D,112

Shift Registers Overview

The 74AHCT594D,112 is an 8-bit serial-in, parallel-out shift register with an output storage register. It operates on a wide supply voltage range from 2.0 V to 5.5 V and features balanced propagation delays. The device includes Schmitt-trigger action at all inputs for noise immunity and overvoltage tolerant inputs up to 5.5 V. It provides independent clocks (SHCP and STCP) and direct overriding clears (SHR and STR) for both the shift and storage registers. A serial output (Q7S) facilitates cascading. The component is specified in compliance with JEDEC standard No. 7-A.

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 active LOW direct overriding clears for shift and storage stages
• All inputs feature Schmitt-trigger action and are overvoltage tolerant to 5.5 V
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level A

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 package type and tape/reel specifications. Ensure compatibility with system voltage levels, as the AHCT series requires a minimum of 4.5 V. Confirm that the SO16 plastic small outline package meets PCB layout requirements. Check current product status to ensure availability before finalizing designs.

Shift Registers Selection Notes

Select this component when TTL-level input compatibility is required within a CMOS environment. The AHCT logic family ensures pin compatibility with Low-Power Schottky TTL while offering high-speed operation. Consider the separate clock inputs if independent shifting and latching timing is necessary. Verify thermal dissipation limits for the SO16 package under maximum operating conditions.

Shift Registers Part Context

This part belongs to the 74AHC/AHCT594 family of 8-bit shift registers with output registers. It shares functional similarities with the 74HC594 but utilizes AHCT input levels compatible with TTL standards. The device is designed for high-speed applications requiring robust noise immunity and flexible clocking options for data serialization tasks.

Shift Registers Replacement Considerations

The 74AHCT594D,118 is a verified substitute part number within the same family, sharing identical electrical characteristics and functionality. Both variants utilize the SO16 package and maintain pin compatibility.
