Quad 2-Input XOR — what this part does
The Texas Instruments SN74ALS86NE4 is a quad 2-input exclusive-OR gate from the 74ALS logic family. Each of the four independent gates performs the Boolean XOR function, outputting a high level when the two inputs differ. This part is used in parity checkers, arithmetic logic units, and data-comparison circuits where a difference between two digital signals needs to be flagged.
Lifecycle and sourcing reality
The SN74ALS86NE4 carries an Active lifecycle status, meaning TI continues to manufacture it. No end-of-life notice or last-time-buy window is in effect. For a BOM line that needs this exact DIP-package XOR gate, the supply channel is the standard distribution network.
