SN74LS164NG4

Shift Registers Overview

The SN74LS164NG4 is an 8-bit serial-in parallel-out shift register from the Texas Instruments SN74LS164 series. It utilizes Low-Power Schottky (LSTTL) bipolar logic technology and is housed in a 14-pin DIP package. The device operates within a supply voltage range of 4.75V to 5.25V and supports a commercial temperature range of 0°C to 70°C. Key electrical characteristics include a propagation delay of 32ns and push-pull outputs. It features two AND-gated serial data inputs and a low-level asynchronous reset function.

Shift Registers Feature Summary

• Converts serial input data into parallel output across eight bits using clocked shifting.
• Includes two AND-gated serial data inputs that allow flexible control over data entry.
• Provides a low-level asynchronous master reset pin to force all outputs to a low state immediately.

Shift Registers Applications

• Serial-to-parallel data conversion for digital systems
• Driving LED displays or indicator arrays
• Generating sequential timing signals

Shift Registers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the required 14-pin DIP form factor. Ensure the logic family corresponds to LSTTL requirements for your circuit design. Check for RoHS compliance status if environmental regulations apply to your assembly process.

Shift Registers Selection Notes

Select this component when LSTTL compatibility is required for existing TTL-based designs. It serves as a direct replacement for standard 74LS164 devices. Consider the 32ns propagation delay and 5V operating voltage constraints. Verify that the DIP packaging fits the available board space and assembly method.

Shift Registers Part Context

This part belongs to the SN74LS164 family of 8-bit shift registers manufactured by Texas Instruments. The 'N' suffix indicates a plastic DIP package, while 'G4' typically denotes specific manufacturing or compliance attributes defined by the manufacturer. It is part of the broader 74-series logic ecosystem designed for general-purpose digital applications.

Shift Registers Replacement Considerations

Direct substitutes include SN74LS164N and SN74LS164DR. CMOS equivalents like SN74HC164 offer similar functionality with different voltage and speed characteristics but may require level shifting or power supply adjustments.
