SN74LV126APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV126APWR is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and features independent line drivers. The device supports mixed-mode voltage operation, allowing inputs to accept voltages up to 5.5V regardless of the VCC level. It includes Ioff circuitry for partial power-down mode support and back drive protection. The component is housed in a 14-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffers with 3-state outputs controlled by individual OE inputs.
• Supports live insertion and partial power-down modes through Ioff functionality.
• Enables down voltage translation as inputs are tolerant to 5.5V across all valid VCC levels.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PW' confirms the TSSOP-14 package type. Confirm RoHS compliance status via the manufacturer's current packaging addendum. Ensure the part number matches the active production status listed in official documentation before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for bus interface applications requiring low-drive CMOS characteristics to minimize output ringing. It is suitable for translating signals between different voltage domains where input tolerance exceeds the operating supply voltage. Consider thermal resistance metrics if operating at high ambient temperatures.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LV126A family of quadruple bus buffer gates. It shares functional similarities with other LV logic series components but is distinct in its specific voltage tolerance and 3-state control architecture designed for bus-oriented systems.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down conditions?

The Ioff feature prevents damage by limiting leakage currents when VCC is zero or undefined, supporting live insertion and back drive protection.

What is the maximum input voltage tolerance?

Inputs are 5.5V tolerant at any valid VCC, allowing the device to translate down from 5.5V signals even when operating at lower supply voltages.
