| 3 | 2Y0 | output | Buffer output 2Y0 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current. |
| 4 | 1A1 | input | Data input for buffer channel 1A1; the recommended input voltage range is 0 V to 5.5 V. |
| 5 | 2Y1 | output | Buffer output 2Y1 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current. |
| 6 | 1A2 | input | Data input for buffer channel 1A2; the recommended input voltage range is 0 V to 5.5 V. |
| 7 | 2Y2 | output | Buffer output 2Y2 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current. |
| 8 | 1A3 | input | Data input for buffer channel 1A3; the recommended input voltage range is 0 V to 5.5 V. |
| 9 | 2Y3 | output | Buffer output 2Y3 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current. |
| 10 | GND | power_in | Ground reference for the device. |
| 11 | 2A3 | input | Data input for buffer channel 2A3; the recommended input voltage range is 0 V to 5.5 V. |
| 12 | 1Y3 | output | Buffer output 1Y3 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current. |
| 13 | 2A2 | input | Data input for buffer channel 2A2; the recommended input voltage range is 0 V to 5.5 V. |
| 14 | 1Y2 | output | Buffer output 1Y2 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current. |
| 15 | 2A1 | input | Data input for buffer channel 2A1; the recommended input voltage range is 0 V to 5.5 V. |
| 16 | 1Y1 | output | Buffer output 1Y1 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current. |
| 17 | 2A0 | input | Data input for buffer channel 2A0; the recommended input voltage range is 0 V to 5.5 V. |
| 18 | 1Y0 | output | Buffer output 1Y0 (3-state capable); the Y port is rated -0.5 V to VCC+0.5 V in the high or low state and ±50 mA continuous output current. |
| 19 | 2OE | input | Active-low output enable; pulling 2OE high places all outputs in 3-state mode, per the pin description on page 4. |
| 20 | VCC | power_in | Supply voltage; the datasheet specifies 1.65 V ≤ VCC ≤ 5.5 V. |
