SN74HC164APW

Shift Registers Overview

The SN74HC164APW is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It belongs to the SN74HC164 series and utilizes high-speed CMOS technology. The device features a 14-pin TSSOP surface-mount package. It operates with a supply voltage range of 2 V to 6 V. The component supports asynchronous reset functionality and includes gated serial inputs for data control. It is designed for industrial temperature ranges, typically operating between -40°C and +85°C.

Shift Registers Feature Summary

• Converts serial input data into parallel output states using clocked shifting operations.
• Provides complete control over incoming data through dual gated serial inputs (A and B).
• Features asynchronous reset capability to clear all outputs independently of the clock signal.

Shift Registers Applications

• Serial-to-parallel data conversion in digital communication interfaces.
• Driving LED displays or indicator arrays from microcontroller serial ports.
• Expanding I/O capabilities for logic circuits requiring additional parallel outputs.

Shift Registers Procurement Notes

Verify the specific suffix 'APW' against the official Texas Instruments datasheet to confirm the exact temperature grade and package variant. Ensure compatibility with the target system's voltage levels and interface requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Shift Registers Selection Notes

Select this component when an 8-bit parallel output expansion is required from a serial source within the HC logic family. Consider the TSSOP-14 package constraints for PCB layout. Verify that the 2 V to 6 V operating range matches the system power supply. Check if the asynchronous reset feature aligns with the system initialization sequence.

Shift Registers Part Context

This component is part of the broader SN74HC164 family of 8-bit shift registers. It shares functional similarities with other variants like SN74HC164DR or SN74HC164PW but differs in package type and potentially temperature rating. The 'A' prefix often denotes an automotive or extended temperature grade in TI nomenclature, requiring verification against the specific datasheet revision.

Shift Registers Replacement Considerations

Direct substitutes include SN74HC164PW or SN74HC164DR from Texas Instruments, provided the package and temperature specifications are compatible. Other manufacturers offer pin-compatible alternatives such as MC74HC164ANG, though package differences must be addressed.
