SN74LVC126APW is a quad non-inverting buffer with 3-state outputs.
Output drive and 3-state control
Each of the four elements handles one bit, with a dedicated output-enable pin per channel. The 24 mA output current at both high and low levels is typical for 74LVC — enough for point-to-point signalling and light fan-out, but not for heavy capacitive loads or driving long backplane traces without a bus transceiver. The 3-state outputs allow multiple buffers to share a common bus line when the enable pins are gated externally.
Temperature grade and environment
The 125°C ceiling is the same as the AEC-Q100 Grade 1 limit, though this specific variant does not carry AEC-Q100 qualification in the listing. For under-hood or engine-bay use, verify the qualification separately or select the automotive-grade 74LVC parts with the 'Q1' suffix.
Package and footprint
14-TSSOP package with 4.40 mm body width.
