Product details

Dual buffer with 3-state outputs — supply range is the headline

Its supply voltage range of 1.65V to 5.5V means it can interface directly with 1.8V, 2.5V, 3.3V, and 5V logic domains without external level shifters — a common need when mixing legacy 5V peripherals with a 3.3V controller. Each buffer element handles one bit and can source or sink 32mA, enough to drive a standard logic input fan-out of ten or a small LED indicator.

Package and footprint — compact 8-VFSOP

Housed in an 8-VFSOP package measuring 2.30mm wide (0.091"), this part is built for dense PCB layouts where board area is tight. The supplier device package is 8-VSSOP, so the footprint is the same as a standard VSSOP-8. Surface-mount assembly is straightforward with standard reflow profiles.

Lifecycle — active, no end-of-life concern

The base product number is 74LVC2G126, so if you ever need a different package variant, the family shares the same logic core.

Frequently asked questions

Is 74LVC2G126DCUTG4 compatible with 3.3V logic?

Yes. The 1.65V to 5.5V supply range covers 3.3V operation directly. At 3.3V VCC, the input thresholds are TTL-compatible, and the 32mA output drive is more than enough to meet 3.3V logic family input requirements.
