SN74LVC126ADRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC126ADRE4 is a hex buffer and line driver from Texas Instruments, featuring four non-inverting buffers with three-state outputs. It operates within a supply voltage range of 1.65V to 3.6V and supports input voltages up to 5.5V, enabling compatibility in mixed 3.3V and 5V systems. The device provides high drive capability with output currents of 24mA at both high and low states. It is housed in a 14-pin SOIC package (SOIC-Narrow-16 equivalent) and functions reliably across an extended industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix 'E4' which indicates lead-free status and RoHS compliance. Confirm the package type corresponds to the SOIC-14 variant. Ensure the operating temperature range meets specific environmental requirements. Cross-reference with the official Texas Instruments datasheet for SN74LVC126A to validate pinout and electrical characteristics before integration into design specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require buffering signals between different voltage domains, specifically 3.3V and 5V systems. The three-state output allows multiple devices to share a common bus without interference. Consider the 24mA drive strength for driving capacitive loads or longer traces. Verify that the SOIC package fits the available PCB footprint and that the -40°C to +85°C temperature range satisfies the application's thermal constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC126A family of quad bus buffers with three-state outputs. The 'E4' suffix denotes a lead-free and RoHS-compliant version manufactured by Texas Instruments. It is part of the broader LVC logic series designed for low-voltage applications. The component serves as a standard interface solution for managing data flow in digital systems where signal integrity and voltage translation are critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74LVC126ADBR and SN74LVC126ARGYR, which offer identical logical functionality but differ in packaging (SSOP and VQFN respectively). When replacing, ensure the new package matches the physical board layout. Verify that the replacement part maintains the same 1.65V to 3.6V operating voltage and 5.5V input tolerance specifications.
