Product details

Dual buffer with 3-state outputs — the 74LVC2G126DCTRG4

Each of the two elements handles one bit, delivering 32 mA source and sink drive per channel across a supply range of 1.65 V to 5.5 V.

If your design lives in a climate-controlled rack, the commercial-grade sibling may save a few cents, but for outdoor telecom, engine bay, or factory-floor duty, this temperature grade is the one that avoids a field failure.

SM8 package — footprint and routing

The SM8 package (8-lead SSOP/MSOP with 2.80 mm body width) is a compact surface-mount footprint suited for dense PCBs. The 0.65 mm pin pitch is fine for hand-assembly but benefits from a solder stencil for reflow. No exposed thermal pad here — dissipation is through the leads, so keep the trace width adequate for the 32 mA per channel if both buffers are active simultaneously.

No last-time-buy risk to plan for on this order code.

Frequently asked questions

Is the 74LVC2G126DCTRG4 a direct replacement for SN74LVC2G126DCTR?

The SN74LVC2G126DCTR is the same base device from Texas Instruments in the same SM8 package. The 74LVC2G126DCTRG4 variant includes the RoHS-compliant 'G4' suffix — functionally identical, same footprint, same electrical specs. It is a drop-in replacement for the non-G4 version.
