Single 3-input XOR in a 1x1 mm footprint
The SN74LVC1G386DSFR: Propagation delay is 4 ns at 5V with a 50 pF load, which keeps timing closure straightforward in most glue-logic paths. Output drive is rated 32 mA for both high and low states, enough to directly switch a small LED or drive a short cable stub without a buffer.
Temperature range and industrial fit
The 74LVC series is known for low quiescent current — here 10 µA max — so the gate adds negligible idle draw in battery-backed or always-on circuits.
