Product details

The SN74LVC1G126DRYR provides a symmetric 32 mA source and sink drive. The 3-state output lets you share a bus line — pull OE high to enable, low to put the output in high-impedance.

The supplier device package is 6-SON (1.45 x 1.0 mm), a small-outline no-lead package with a 0.5 mm pitch. It is surface-mount only and requires a solder-paste stencil with apertures sized for the exposed pad — the datasheet's recommended land pattern is the reference. The package is leadless, so visual inspection of the solder joints is difficult; X-ray or automated optical inspection is the usual check.

Frequently asked questions

What is the closest pin-compatible alternative to SN74LVC1G126DRYR?

Within the same 74LVC family, the SN74LVC1G126DCKR (SC-70 package) and SN74LVC1G126DBVR (SOT-23 package) are functionally identical but in different footprints — they are not pin-compatible with the 6-UFDFN. For a drop-in replacement in the same 6-SON package, check the SN74LVC1G126DRLR (same 6-SON, different reel suffix). Verify the land pattern against the datasheet before substituting.
