SN74AHC164PWR

Shift Registers Overview

The SN74AHC164PWR is an 8-bit parallel-out serial shift register from the Texas Instruments AHC logic family. It operates within a supply voltage range of 2V to 5.5V and features two AND-gated serial inputs (A and B) alongside an asynchronous clear (CLR) input. The device utilizes push-pull outputs and shifts data on the rising edge of the clock signal. It is housed in a 14-pin TSSOP package with a maximum propagation delay of 14ns at 5V.

Shift Registers Feature Summary

• Features balanced CMOS push-pull outputs for efficient current sourcing and sinking capabilities.
• Includes latching logic circuitry that retains volatile memory states while power is applied.
• Utilizes standard CMOS inputs requiring fast transition rates to prevent oscillations.

Shift Registers Applications

• Increasing the number of available outputs on a microcontroller
• Temporarily storing up to 8 bits of data
• Controlling seven-segment displays

Shift Registers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-14 package configuration required for your design. Confirm that the component meets the recommended operating conditions, specifically the supply voltage range and temperature specifications, before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is needed without complex communication interfaces. It is suitable for designs requiring simple GPIO control via two serial inputs and a clock line. Ensure the load capacitance does not exceed 50pF to maintain specified performance characteristics.

Shift Registers Part Context

This part belongs to the SN74AHC164 series of 8-bit shift registers manufactured by Texas Instruments. The 'PWR' designation indicates the specific tape-and-reel packaging variant of the PW (TSSOP) package type. It is part of the broader AHC logic family designed for high-speed digital applications.

Shift Registers Replacement Considerations

Compatible alternatives include other 8-bit serial-in parallel-out shift registers such as the SN74HC164 or SN74LV164, provided pin compatibility and electrical specifications align with the system requirements.
