SN74AC164PWRQ1

Shift Registers Overview

The SN74AC164PWRQ1 is an automotive-grade, 8-bit serial-in and parallel-out shift register from Texas Instruments. It belongs to the AC logic family and operates within a supply voltage range of 2 V to 6 V. The device features two serial data inputs (A and B) that are ANDed together, providing a single serial input path for clocking data into the eight D-type flip-flops. It utilizes a push-pull output configuration and is housed in a TSSOP-14 package. Designed for high-speed applications, it supports mixed-mode operation and meets AEC-Q100 qualification standards for automotive environments.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle electronics.
• High-speed AC logic performance enabling efficient data shifting in demanding operational conditions.
• Dual serial inputs (A and B) internally ANDed to simplify serial data entry control.

Shift Registers Applications

• Automotive infotainment systems requiring robust serial-to-parallel conversion.
• Vehicle body control modules utilizing high-reliability logic components.
• Industrial automotive interfaces needing extended temperature range operation.

Shift Registers Procurement Notes

Verify the specific suffix 'PWR' indicates the TSSOP-14 package and reel/cut-tape availability. Confirm AEC-Q100 certification status through official Texas Instruments documentation or authorized distributor datasheets. Ensure the design accounts for the 2 V to 6 V operating voltage range and check for any recent product change notices affecting pinout or electrical characteristics.

Shift Registers Selection Notes

Select this component when automotive grade reliability is required alongside high-speed AC logic performance. It serves as a direct replacement for non-automotive SN74AC164 variants where AEC-Q100 compliance is mandatory. Consider the TSSOP-14 footprint constraints and the specific 2 V to 6 V power supply requirements of the target circuit design.

Shift Registers Part Context

This part is part of the SN74AC164 series, which provides 8-bit serial-in/parallel-out shifting capabilities. The 'Q1' suffix denotes automotive qualification, while 'PWR' specifies the surface-mount TSSOP-14 packaging. It complements other automotive logic devices like the SN74AC138PWRQ1 decoder for comprehensive system integration in vehicle electronics.

Shift Registers FAQ

What is the function of the A and B inputs?

The A and B inputs are serial data inputs that are internally ANDed. Data is shifted into the register on the positive edge of the clock pulse only when both inputs are high.

Is this device suitable for harsh automotive environments?

Yes, the SN74AC164PWRQ1 is qualified to AEC-Q100 standards, ensuring reliability under the thermal and electrical stresses typical of automotive applications.
