Output enable and bus isolation
The SN74AHCT1G126DBVT: The 3-state output goes high-impedance when the output enable pin is deasserted, preventing bus contention.
Supply and temperature coverage
Rated for 4.5V to 5.5V, this buffer is a direct fit for 5V TTL/CMOS logic rails. The SOT-23-5 footprint matches standard 5-pin small-outline transistor layouts, simplifying PCB layout reuse.
