Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Active-low output enable for buffer 1; the output is disabled (high-impedance) when OE is high, and OE should be tied to VCC through a pullup resistor to hold the high-impedance state during power up or power down. |
| 2 | 1A | input | Data input of buffer 1, which accepts voltages up to 5.5V. |
| 3 | 1Y | output | 3-state output of buffer 1, rated for ±24mA output drive at VCC=3.0V and ±50mA continuous output current. |
| 4 | 2OE | input | Active-low output enable for buffer 2; the output is disabled (high-impedance) when OE is high, and OE should be tied to VCC through a pullup resistor to hold the high-impedance state during power up or power down. |
| 5 | 2A | input | Data input of buffer 2, which accepts voltages up to 5.5V. |
| 6 | 2Y | output | 3-state output of buffer 2, rated for ±24mA output drive at VCC=3.0V and ±50mA continuous output current. |
| 7 | GND | power_in | Ground reference for the device. |

| 10 | 3OE | input | Active-low output enable for buffer 3; the output is disabled (high-impedance) when OE is high, and OE should be tied to VCC through a pullup resistor to hold the high-impedance state during power up or power down. |
| 11 | 4Y | output | 3-state output of buffer 4, rated for ±24mA output drive at VCC=3.0V and ±50mA continuous output current. |
| 12 | 4A | input | Data input of buffer 4, which accepts voltages up to 5.5V. |
| 13 | 4OE | input | Active-low output enable for buffer 4; the output is disabled (high-impedance) when OE is high, and OE should be tied to VCC through a pullup resistor to hold the high-impedance state during power up or power down. |
| 14 | VCC | power_in | Power supply, operating range 1.65V to 5.5V. |
