Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver Output: if A > B by 200mV, RO will be high; if A < B by 200mV, RO will be low. |
| 2 | RE | input | Receiver Output Enable: RO is enabled when RE is low, and RO is high impedance when RE is high. |
| 3 | DE | input | Driver Output Enable: the driver outputs (Y and Z, pins A and B when DE is high) are enabled by bringing DE high and are high impedance when DE is low. |
| 4 | DI | input | Driver Input: a low on DI forces output Y low and output Z high, and a high on DI forces output Y high and output Z low. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Noninverting Receiver Input and Noninverting Driver Output. |
| 7 | B | bidirectional | Inverting Receiver Input and Inverting Driver Output. |
| 8 | VCC | power_in | Positive Supply: 4.75V ≤ VCC ≤ 5.25V. |
