Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output: RO is high when A-B is at least 200mV and low when A-B is at most -200mV, and it is high if the inputs are open, shorted or undriven for more than 2µs, with RO enabled only when RE is low. |
| 2 | RE | input | Receiver output enable (hot swap): RO is enabled when RE is low and goes high-impedance when RE is high, and RE should be high with DE low to enter shutdown mode. |
| 3 | DE | input | Driver output enable (hot swap): the driver outputs are enabled when DE is high and high-impedance when DE is low, and DE should be low with RE high to enter shutdown mode. |
| 4 | DI | input | Driver input: with DE high, a low on DI forces the non-inverting output (A/Y) low and the inverting output (B/Z) high, and a high on DI forces A/Y high and B/Z low. |
| 5 | GND | power_in | Power ground. |
| 6 | A/Y | bidirectional | Non-inverting receiver input and non-inverting driver output. |
| 7 | B/Z | bidirectional | Inverting receiver input and inverting driver output. |
| 8 | VCC | power_in | 3.0V to 5.5V power supply input; bypass to ground with a 0.1µF capacitor. |
