Product details

Active single-gate buffer with 3-state output

The 74LVC1G126DCKRG4: The output can be placed in a high-impedance state via the output-enable pin, allowing multiple drivers to share a common bus line.

Housed in a 5-lead SC-70-5 package (also listed as SOT-353), this is a small surface-mount part. The SC-70 body is low-profile and thermally light, so it reflows cleanly with a standard lead-free profile. If you need to replace one on a board, the small thermal mass means it lifts cleanly with hot air and minimal risk of lifting the pad.

Frequently asked questions

Is 74LVC1G126DCKRG4 compatible with 3.3V logic?

Yes, the 74LVC1G126DCKRG4 operates from 1.65 V to 5.5 V, so it is fully compatible with 3.3 V logic levels. The 32 mA output drive at both high and low levels ensures reliable signal integrity on a 3.3 V bus.

What is the closest pin-compatible alternative to 74LVC1G126DCKRG4 in this component family?

Within the 74LVC family, the 74LVC1G125 is a pin-compatible alternative that differs only in the output-enable polarity: the 74LVC1G126 has an active-high enable, while the 74LVC1G125 uses an active-low enable. Both share the same SC-70-5 footprint and supply range.
