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. |
