Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Ḡ | input | Active-low output enable input; high puts output Y in high impedance, low passes A to Y; 5.5 V tolerant and must be tied to VCC or GND if unused. |
| 2 | A | input | Data input (IN A) of the bus buffer, 5.5 V tolerant, with VIN absolute maximum of -0.5 to 6.0 V. |
| 3 | GND | power_in | Ground reference (0 V) for the device. |
| 4 | Y | tri_state | 3-state buffer output (OUT Y) with ±24 mA (min) drive at VCC = 3.0 V and 5.5 V power-down protection. |
| 5 | VCC | power_in | Supply voltage pin, operating range 1.65 to 5.5 V, absolute maximum -0.5 to 6.0 V. |
