SN74LV164DR

Shift Registers Overview

The SN74LV164DR is an 8-bit parallel-out serial shift register from Texas Instruments, belonging to the LV logic series. It operates on a single circuit with push-pull outputs and accepts serial data via two gated inputs (A and B). The device supports a supply voltage range of 2 V to 5.5 V and functions within an operating temperature range of -40°C to +125°C. It is housed in a surface-mount 14-VSSOP package.

Shift Registers Feature Summary

• Converts serial input data into parallel output states for digital systems
• Features dual gated serial inputs (A and B) for precise data control
• Supports mixed-mode voltage operation across a wide supply range

Shift Registers Applications

• Industrial control systems requiring serial-to-parallel conversion
• Automotive electronics utilizing low-voltage logic interfaces
• Consumer devices needing compact shift register solutions

Shift Registers Procurement Notes

Verify the specific suffix 'DR' corresponds to the 14-VSSOP package and tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the manufacturer part number matches official Texas Instruments documentation before procurement to avoid counterfeit components.

Shift Registers Selection Notes

Select this component when a robust 8-bit shift register is required for automotive or industrial environments. The LV series offers lower power consumption compared to standard TTL while maintaining compatibility with 5V logic levels. Ensure the application requires serial-to-parallel functionality rather than parallel-in or bidirectional shifting capabilities.

Shift Registers Part Context

This part belongs to the SN74LV164A family of 8-bit parallel-out serial shift registers. It is designed for high-speed applications requiring low power dissipation. The device integrates clocked D-type flip-flops with serial data inputs and eight parallel outputs, suitable for driving displays or latching data in complex digital circuits.

Shift Registers FAQ

What is the function of the A and B inputs?

The A and B inputs are serial data inputs that must both be high to enable data entry on the rising edge of the clock pulse.

Does this device support parallel loading?

No, the SN74LV164 is a serial-in parallel-out shift register and does not have dedicated parallel load pins.
