74AHCT594PW,112

Shift Registers Overview

The Nexperia 74AHCT594PW,112 is an 8-bit serial-in, parallel-out shift register with a 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 inputs for high noise immunity and overvoltage tolerant inputs up to 5.5 V. It utilizes separate clocks (SHCP and STCP) and direct overriding clears (SHR and STR) for both the shift and storage registers. The component is specified in compliance with JEDEC standard No. 7-A and is pin compatible with Low-Power Schottky TTL.

Shift Registers Feature Summary

• Provides independent direct overriding clears for both shift and storage registers
• Features separate positive-edge triggered clocks for shift and storage operations
• Includes Schmitt-trigger action at all inputs for improved noise immunity
• Supports cascading via a dedicated serial output pin

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and tape/reel specifications. Confirm that the 74AHCT594PW,112 variant meets the required temperature range and logic level standards for the target application before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when TTL-compatible input levels are required within a CMOS system. The 74AHCT series ensures compatibility with Low-Power Schottky TTL while offering the benefits of CMOS technology. Ensure the design accommodates the separate clock and clear signals provided by the architecture.

Shift Registers Part Context

This part belongs to the 74AHC/AHCT594 family of 8-bit shift registers with output registers. The PW suffix indicates a TSSOP16 plastic thin shrink small outline package. The AHCT designation specifies TTL input levels, distinguishing it from the AHC variant which uses CMOS input levels.

Shift Registers Replacement Considerations

The 74AHCT594PW,118 is a verified substitute part number within the same product family.
