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.","metaTitle":"74LVC1G126DCKRG4 Buffer, Non-Inverting, 3-State, 1.65V-5.5V","metaDescription":"Texas Instruments 74LVC1G126DCKRG4 single buffer with 3-state output, 32mA drive, SC-70-5.

The 32 mA output drive at both high and low levels ensures reliable signal integrity on a 3.3 V bus."},{"question":"What is the closest pin-compatible alternative to 74LVC1G126DCKRG4 in this component family?","answer":"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.
