The 7410 (variants 74LS10, 74HC10) is a 74-series logic IC with three independent 3-Input NAND gates.
.--\/--.
1A -> |01 14| -- +5V
1B -> |02 13| <- 1C
2A -> |03 12| -> 1Y
2B -> |04 11| <- 3C
2C -> |05 10| <- 3B
2Y <- |06 09| <- 3A
Gnd -- |07 08| -> 3Y
`------'
Y is low if all of A, B and C are high, and is high if any of A, B or C is low.
