Product details

Single-gate buffer for mixed-voltage buses

The SN74LVC1G126DCKR is a single non-inverting buffer with 3-state output.

At 1.8V it interfaces directly with low-voltage ASICs or FPGAs; at 3.3V or 5V it matches legacy logic. No external level translator is needed when the buffer's supply matches the downstream rail. The 32 mA symmetrical drive at both logic levels keeps rise and fall times balanced, which simplifies timing closure on a shared bus. If the load exceeds 32 mA per pin, buffer the output with a discrete transistor or use a higher-drive gate.

Frequently asked questions

What is the closest pin-compatible alternative to SN74LVC1G126DCKR?

Within the 74LVC family, the SN74LVC1G125DCKR is the inverting equivalent with the same pinout and supply range. For a non-inverting buffer with identical footprint, the SN74LVC1G126 is the direct match; no alternative part number is needed unless the output polarity must change.
