Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output; RO is high impedance when RE is high, and the datasheet states it is logic-high when the receiver differential input VOD is at or above -10mV on the MAX14841E. |
| 2 | RE | input | Active-low receiver output enable: driving RE low enables RO, and driving RE high with DE low puts the device into low-power shutdown mode (under 10µA supply current); RE is a hot-swap input. |
| 3 | DE | input | Driver output enable: driving DE high enables the driver outputs, which are high impedance when DE is low; DE is a hot-swap input and driving RE high with DE low enters shutdown. |
| 4 | DI | input | Driver input: with DE high, a low on DI forces output A low and output B high, and a high on DI forces A high and B low. |
| 5 | GND | power_in | Ground reference for the device; all voltages are referenced to this pin. |
| 6 | A | bidirectional | Noninverting receiver input and noninverting driver output; the absolute maximum rating for A and B is -8.0V to +13.0V referenced to GND. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output; the absolute maximum rating for A and B is -8.0V to +13.0V referenced to GND. |
| 8 | VCC | power_in | Positive supply voltage input, specified at 3.0V to 3.6V; bypass VCC to GND with a 0.1µF ceramic capacitor. |
