SN74LV164ADBR

Shift Registers Overview

The SN74LV164ADBR is an 8-bit parallel-out serial shift register from the Texas Instruments SN74LV164A series. It operates on a single CMOS logic family with a supply voltage range of 2 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. It supports mixed-mode voltage operation and includes overvoltage protection on inputs. The component is housed in a 14-SOIC package and functions within a temperature range of -40°C to +125°C.

Shift Registers Feature Summary

• Converts serial input data into eight parallel output bits using a single clock cycle per bit.
• Supports mixed-mode voltage operation allowing interfacing between different voltage domains.
• Provides overvoltage protection on all input pins to safeguard against signal spikes exceeding the supply rail.

Shift Registers Applications

• Serial-to-parallel data conversion in communication interfaces
• Driving LED displays or indicator arrays from microcontroller serial ports
• Expanding I/O capabilities for digital control systems

Shift Registers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the 14-SOIC package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected distributor provides traceable origin for automotive or industrial grade requirements if applicable.

Shift Registers Selection Notes

Select this component when low power consumption and wide operating voltage are required. The LV series offers faster propagation delays compared to standard HC logic while maintaining compatibility. Consider the SOIC package for standard surface mount assembly processes requiring moderate pin density.

Shift Registers Part Context

This part belongs to the SN74LV164A family of 8-bit shift registers. It shares functional compatibility with other 74LV164 variants but differs in packaging and specific electrical characteristics defined by the LV logic family. It serves as a direct replacement for older 74LS164 designs where lower voltage operation is needed.

Shift Registers Replacement Considerations

SN74LV164APWR is a compatible alternative in TSSOP-14 packaging. SN74HC164PWR offers similar functionality in the HC logic family with slightly different electrical specifications.
