SN74AHCT165PWR

Shift Registers Overview

The SN74AHCT165PWR is an 8-bit parallel-load shift register with TTL-compatible inputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features balanced CMOS push-pull outputs capable of sourcing and sinking up to 8 mA. The device includes separate clocks for the shift and storage registers, a direct overriding clear input, and serial output for cascading. Propagation delay is typically 7 ns at 25 °C and 5 V. It supports operating temperatures from -40 °C to +125 °C and is housed in a 16-pin TSSOP package.

Shift Registers Feature Summary

• TTL-compatible CMOS inputs designed for interfacing with standard logic devices
• Balanced CMOS push-pull outputs providing equal source and sink current capabilities
• Separate clock inputs for independent control of shift and storage registers

Shift Registers Applications

• Network Switches
• Power Infrastructures
• LED Displays
• Servers

Shift Registers Procurement Notes

Verify that the ordering suffix 'PWR' corresponds specifically to the PW (TSSOP-16) package variant as documented in the manufacturer's datasheet. Confirm that the component meets the required AEC-Q100 or general industrial qualification standards if applicable to your specific system design. Ensure compatibility with the specified 4.5-V to 5.5-V supply voltage range during procurement validation.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial conversion is required with TTL-compatible input thresholds. It is suitable for applications needing independent shift and storage clocking. Consider the 16-pin TSSOP package for surface-mount assembly. Verify that the load capacitance does not exceed recommended limits to maintain signal integrity and switching performance specifications.

Shift Registers Part Context

This part belongs to the SN74AHC/AHCT165 family of 8-bit parallel-load shift registers. The AHCT series specifically denotes high-speed CMOS technology with TTL-compatible inputs, allowing direct interface with 5-V TTL logic systems. The device provides a reliable solution for expanding digital input channels in microcontroller-based systems through serial data transfer.
