Pinout

Pin Name Type Function
1 1A input Channel 1, Input A. CMOS logic input to gate 1 (buffered). VIH ≥ 3.15 V at VCC = 4.5 V; VIL ≤ 1.35 V at VCC = 4.5 V.
2 1B input Channel 1, Input B. CMOS logic input to gate 1 (buffered).
3 2A input Channel 2, Input A. CMOS logic input to gate 2 (buffered).
4 2B input Channel 2, Input B. CMOS logic input to gate 2 (buffered).
5 2C input Channel 2, Input C. CMOS logic input to gate 2 (buffered).
6 2Y output Channel 2, Output Y. Push-pull CMOS output equal to 2A · 2B · 2C. Sources/sinks up to ±25 mA continuous (±4 mA at VCC = 4.5 V for guaranteed VOH/VOL).
7 GND power_in Ground reference (0 V). Common return for VCC and all logic signals.
8 3Y output Channel 3, Output Y. Push-pull CMOS output equal to 3A · 3B · 3C.
9 3A input Channel 3, Input A. CMOS logic input to gate 3 (buffered).
10 3B input Channel 3, Input B. CMOS logic input to gate 3 (buffered).
11 3C input Channel 3, Input C. CMOS logic input to gate 3 (buffered).
12 1Y output Channel 1, Output Y. Push-pull CMOS output equal to 1A · 1B · 1C.
13 1C input Channel 1, Input C. CMOS logic input to gate 1 (buffered).
14 VCC power_in Positive supply rail. Recommended 2 V to 6 V (nom 5 V); absolute max 7 V. Bypass to GND with a 100 nF ceramic close to the pin.
