It takes two inputs and drives the output high when they differ. In a 1.8V or 2.5V digital rail, this is the gate you reach for when you need a parity check, a controlled inverter (tie one input high), or a glitch-free comparator on a fast signal path. The SC-70-5 package is small enough for cramped boards but still hand-solderable with a fine tip — no lab bench required for a field swap. ## Supply voltage and signal compatibility This part runs on a supply from 0.8V up to 2.7V, which covers the common 1.8V and 2.5V logic levels used in modern FPGAs, MCUs, and memory interfaces. The input logic low threshold is 0V to 0.7V, and the high threshold is 1.7V — meaning a 1.8V CMOS signal drives it cleanly, and a 2.5V signal has plenty of margin. No level translator needed between this gate and a 1.8V or 2.5V bus; it is native to those rails. ## Speed and drive Maximum propagation delay is 2ns at 2.5V with a 30pF load. Output drive is 9mA source and 9mA sink. ## Lifecycle and sourcing No end-of-life notice or last-time-buy on record. For dual-sourcing or a pin-compatible alternate, the SN74AHC1G32DCKT is an OR gate in the same package but runs on a higher supply range (2V to 5.5V) and is not a direct XOR substitute.","metaTitle":"SN74AUC1G86DCKR XOR Gate, 2-Input, SC-70-5, 0.8V–2.7V","metaDescription":"TI SN74AUC1G86DCKR single 2-input XOR gate in SC-70-5.
