Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1A | input | Input A of NAND gate 1; accepts TTL-compatible input voltage with VIH ≥ 2V and VIL ≤ 0.8V. |
| 2 | 1B | input | Input B of NAND gate 1; accepts TTL-compatible input voltage with VIH ≥ 2V and VIL ≤ 0.8V. |
| 3 | 1Y | output | Output of NAND gate 1; delivers ±24 mA at VOH ≥ 4.4V (@ IOH = -24mA) and VOL ≤ 0.4V (@ IOL = 24mA). |
| 4 | 2A | input | Input A of NAND gate 2; accepts TTL-compatible input voltage with VIH ≥ 2V and VIL ≤ 0.8V. |
| 5 | 2B | input | Input B of NAND gate 2; accepts TTL-compatible input voltage with VIH ≥ 2V and VIL ≤ 0.8V. |
| 6 | 2Y | output | Output of NAND gate 2; delivers ±24 mA at VOH ≥ 4.4V (@ IOH = -24mA) and VOL ≤ 0.4V (@ IOL = 24mA). |
| 7 | GND | power_in | Ground reference; must be connected to system ground. |
| 8 | 3Y | input | Per Table 3-1: listed as type I with description 'Channel 3, Input B'; however pin name indicates output function. |
| 9 | 3A | output | Per Table 3-1: listed as type O with description 'Channel 3, Output Y'; however pin name indicates input function. |
| 10 | 3B | input | Input for NAND gate 3 per Table 3-1 description 'Channel 3, Input A'; accepts TTL-compatible input voltage with VIH ≥ 2V and VIL ≤ 0.8V. |
| 11 | 4Y | input | Per Table 3-1: listed as type I with description 'Channel 4, Input B'; however pin name indicates output function. |
| 12 | 4A | output | Per Table 3-1: listed as type O with description 'Channel 4, Output Y'; however pin name indicates input function. |
| 13 | 4B | input | Input for NAND gate 4 per Table 3-1 description 'Channel 4, Input A'; accepts TTL-compatible input voltage with VIH ≥ 2V and VIL ≤ 0.8V. |
| 14 | VCC | power_in | Positive supply voltage; 4.5V to 5.5V recommended operating range per section 4.2. |
