SN74HC165N

Shift Registers Overview

The SN74HC165N is an 8-bit parallel-load shift register from the Texas Instruments SN74HC165 series. It features a serial/parallel to serial counting sequence and operates on a single circuit. The device utilizes CMOS logic technology within the HC series, housed in a DIP-16 package. It supports a supply voltage range of 2 V to 6 V and functions across an operating temperature range of -40°C to +125°C. Key electrical parameters include propagation delays of 150 ns, 30 ns, and 26 ns, with nine input lines and one output line.

Shift Registers Feature Summary

• Provides parallel-to-serial data conversion capabilities for digital systems.
• Operates reliably across extended industrial temperature ranges.
• Compatible with standard CMOS logic families.

Shift Registers Applications

• Digital data acquisition systems requiring parallel input expansion.

• Status monitoring interfaces for peripheral devices.

Shift Registers Procurement Notes

Verify the specific suffix 'N' corresponds to the DIP-16 package variant when sourcing. Confirm that the component meets the required AEC-Q100 qualification if automotive compliance is necessary, as this designation typically indicates general-purpose or specific grade availability depending on the manufacturer's current catalog structure.

Shift Registers Selection Notes

Select this component when a robust 8-bit parallel load shift register is needed for general-purpose logic applications. Ensure the design accommodates the specified 2 V to 6 V supply range and that the DIP-16 footprint aligns with the PCB layout constraints. Verify compatibility with the host system's voltage levels and signal integrity requirements at the intended operating frequencies.

Shift Registers Part Context

This part belongs to the widely used SN74HC165 family of 8-bit parallel-load shift registers. It serves as a fundamental building block for expanding digital inputs in microcontroller-based designs. The HC series offers high-speed operation while maintaining low power consumption, making it suitable for various consumer and industrial electronic applications requiring reliable data shifting.

Shift Registers Replacement Considerations

Consider SN74HC165PWG4 or SN74HC165PWR for surface-mount alternatives within the same functional family. Verify pinout compatibility and electrical specifications before substituting with other manufacturers' equivalents such as TC74HC165AF.
