SN74LV126APWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV126APWT 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 live insertion and partial power down protection. The component is housed in a TSSOP-14 package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffers with 3-state outputs controlled by individual OE pins
• Supports mixed-mode voltage operation across all ports for seamless interface between different logic families
• Includes Ioff functionality to prevent excessive current draw during live insertion or partial power-down states

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm status and packaging details. The SN74LV126APWT designation indicates a TSSOP-14 package; however, availability may vary as this specific suffix can be obsolete while active alternatives exist. Confirm RoHS compliance and lead finish specifications directly from the datasheet documentation before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing bus interfaces requiring low-drive CMOS characteristics to minimize output ringing and overshoot. It is suitable for applications needing voltage translation from 5.5V tolerant inputs to lower VCC levels. Ensure unused inputs are tied to GND or VCC to prevent undefined operational states and verify that load conditions do not exceed maximum drive limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV126A family of quadruple bus buffer gates with 3-state outputs. It is designed for 2V to 5.5V VCC operation and is commonly used in digital logic circuits where bus isolation and signal buffering are required. The PW suffix denotes the TSSOP surface-mount package variant.
