SN74ACT164PWRQ1

Shift Registers Overview

The SN74ACT164PWRQ1 is an automotive-grade, 8-bit serial-in/parallel-out shift register from Texas Instruments. It belongs to the ACT logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features two serial data inputs (A and B) and a clock input, converting serial data into parallel outputs on eight pins. It is housed in a 14-pin TSSOP package and is qualified under AEC-Q100 standards for Grade 1, supporting operation temperatures from -40°C to +125°C.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for high reliability in vehicle environments.
• Serial-to-parallel conversion capability using dual serial inputs and a single clock line.
• Robust output drive characteristics typical of the ACT logic family for stable signal transmission.

Shift Registers Applications

• Automotive display driver interfaces requiring serial data expansion.
• Vehicle control unit peripheral expansion for status indication.
• Industrial automation systems operating under strict temperature constraints.

Shift Registers Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-14 package and reel/cut-tape availability. Confirm AEC-Q100 Grade 1 qualification matches project requirements. Ensure voltage levels align with 4.5V–5.5V system rails. Check for RoHS compliance documentation. Validate lead times against automotive production schedules.

Shift Registers Selection Notes

Select this component when an 8-bit parallel output is needed from a serial source in automotive applications. The ACT series offers faster switching speeds than standard LS logic while maintaining CMOS power efficiency. Ensure the design supports the 4.5V minimum supply voltage. Consider the TSSOP-14 footprint for PCB layout compatibility.

Shift Registers Part Context

This part is part of the SN74ACT164-Q1 family of automotive shift registers. It shares functional similarities with other 8-bit serial-in/parallel-out devices but is distinguished by its specific ACT speed grade and automotive environmental ratings. It serves as a bridge between serial communication buses and parallel peripheral interfaces in harsh environments.

Shift Registers Replacement Considerations

SN74AHC164QPWRQ1: Offers similar functionality with a wider voltage range (2V–5.5V) but different speed/power characteristics. SN74ACT164PW: Non-automotive version lacking AEC-Q100 qualification. Verify pinout and electrical parameters before substitution.
