## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Active-low output enable for buffer 1: a low level enables 1Y and a high level places 1Y in the high-impedance state, with inputs rated 0 V to 3.6 V. |
| 2 | 1A | input | Data input to buffer 1, rated 0 V to 3.6 V; unused inputs must be held at VCC or GND. |
| 3 | 2Y | output | Output of buffer 2, which follows 2A while 2OE is low and goes high-impedance while 2OE is high, with VCC range 0.8 V to 3.6 V. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | 2A | input | Data input to buffer 2, rated 0 V to 3.6 V; unused inputs must be held at VCC or GND. |
| 6 | 1Y | output | Output of buffer 1, which follows 1A while 1OE is low and goes high-impedance while 1OE is high, with VCC range 0.8 V to 3.6 V. |
| 7 | 2OE | input | Active-low output enable for buffer 2: a low level enables 2Y and a high level places 2Y in the high-impedance state, with inputs rated 0 V to 3.6 V. |
| 8 | VCC | power_in | Supply voltage, 0.8 V to 3.6 V recommended operating range. |
