74AHC164PW,112

Shift Registers Overview

The Nexperia 74AHC164PW,112 is an 8-bit serial-in/parallel-out shift register housed in a TSSOP14 package (SOT402-1). It features two serial data inputs (DSA and DSB) and eight parallel outputs (Q0 to Q7). Data shifts on LOW-to-HIGH clock transitions. The device operates with a supply voltage range of 2.0 V to 5.5 V and includes overvoltage tolerant inputs up to 5.5 V. It supports temperature ranges from -40 °C to +125 °C and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Shift Registers Feature Summary

• Features Schmitt-trigger actions on all inputs for improved noise immunity.
• Includes an active LOW master reset input that clears the register independently of other inputs.
• Supports mixed voltage environments through overvoltage tolerant inputs.

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems.
• Data storage and buffering applications.
• Interface translation between different voltage logic levels.

Shift Registers Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP14 package variant as documented in the official Nexperia datasheet. Confirm that the required operating temperature range and supply voltage specifications align with your system design constraints before procurement. Ensure compatibility with standard surface mount assembly processes for the SOT402-1 package type.

Shift Registers Selection Notes

Select this component when an 8-bit serial-in/parallel-out shift function is required within a CMOS logic family. The AHC technology offers balanced propagation delays and low power dissipation. Consider the TSSOP14 package if space-constrained surface mounting is necessary. Verify input voltage levels match the CMOS logic standards required by the driving circuitry.

Shift Registers Part Context

This part belongs to the 74AHC164 series of 8-bit shift registers manufactured by Nexperia. It is distinct from the 74AHCT164 variant, which utilizes TTL input levels instead of CMOS levels. The PW suffix specifically denotes the plastic thin shrink small outline package with 14 leads. This component serves as a fundamental building block for sequential logic circuits requiring serial data processing.

Shift Registers Replacement Considerations

Direct functional substitutes include the 74AHC164D (SO14 package) and 74AHC164BQ (DHVQFN14 package) from the same manufacturer. These variants share identical electrical characteristics but differ in physical package dimensions. Ensure the replacement package fits the available PCB footprint and soldering requirements.
