SN74AHCT164QPWRQ1

Shift Registers Overview

The SN74AHCT164QPWRQ1 is an automotive-grade, 8-bit parallel-out serial shift register from Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 30 MHz. The device features two serial data inputs (A and B) and a clear input, packaged in a 14-pin TSSOP. It complies with AEC-Q100 standards for automotive applications, ensuring reliability under specified temperature conditions.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• High-speed operation supporting data rates up to 30 MHz
• Dual serial data inputs for flexible configuration
• Push-pull outputs for robust signal driving

Shift Registers Applications

• Automotive infotainment systems
• Instrument cluster displays
• Body control modules
• Telematics units

Shift Registers Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct voltage range and package type. Confirm AEC-Q100 qualification status if required for specific automotive safety integrity levels. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions prior to final design integration.

Shift Registers Selection Notes

Select this component when an 8-bit shift register is required for automotive environments with strict voltage constraints between 4.5 V and 5.5 V. It is suitable for designs needing high-speed serial-to-parallel conversion with push-pull outputs. Ensure the application does not require lower voltage operation, as the AHCT series is not compatible with standard 3.3 V logic levels without level shifting.

Shift Registers Part Context

This device belongs to the SN74AHC164-Q1 family of automotive shift registers. It shares functional similarities with other members but is specifically optimized for 5 V logic interfaces. The Q1 suffix indicates automotive qualification, while the PWR package denotes a plastic small-outline wide resistor network style with 14 pins.

Shift Registers Replacement Considerations

SN74AHC164QPWRQ1 is a direct pin-compatible alternative within the same family. SN74AHCT164PW is a non-automotive grade equivalent with identical functionality but lacks automotive certification.
