SN74LS164NSR

Shift Registers Overview

The SN74LS164NSR is an 8-bit serial-in, parallel-out shift register from the Texas Instruments SN74LS164 series. It operates on a bipolar logic type within the LS family. The device features a 14-pin SOIC package and supports a supply voltage range of 4.75 V to 5.25 V. It has a propagation delay of 32 ns and functions within a temperature range of 0 °C to +70 °C.

Shift Registers Feature Summary

• Serial-to-parallel data conversion capability
• Asynchronous reset functionality for immediate output clearing
• Push-pull output configuration

Shift Registers Applications

• General-purpose digital logic circuits
• Data storage applications requiring serial input and parallel output
• Industrial control systems operating within standard commercial temperature ranges

Shift Registers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and reel specifications. Ensure compatibility with existing board layouts regarding the SOIC-14 footprint. Confirm that the bipolar LS logic family aligns with system power and interface requirements before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with asynchronous reset is required in a surface-mount format. The LS logic family provides established performance characteristics suitable for standard TTL-compatible designs. Verify that the 32 ns propagation delay meets the timing constraints of the target application circuit.

Shift Registers Part Context

This part belongs to the broader SN74LS164 product line, which includes variants such as the through-hole SN74LS164N and the SOIC-based SN74LS164DR. All variants share the same core logical function but differ in physical packaging and mounting style to accommodate different manufacturing processes.

Shift Registers Replacement Considerations

The SN74LS164DR serves as a direct functional substitute within the same logic family, offering identical electrical characteristics in a similar surface-mount package.
