2 DO1+ output Noninverting RS-422 output of transmitter 1.
3 DO1- output Inverting RS-422 output of transmitter 1.
4 EN input Active-high transmitter enable for all four transmitters: drive HIGH to enable, LOW to three-state the outputs; input is hot-swap protected.
5 DO2- output Inverting RS-422 output of transmitter 2.
6 DO2+ output Noninverting RS-422 output of transmitter 2.
7 DI2 input Transmitter 2 input: when transmitter 2 is enabled, a low forces DO2+ low and DO2- high, and a high forces DO2+ high and DO2- low.
8 GND power_in Ground reference for the device.
9 DI3 input Transmitter 3 input: when transmitter 3 is enabled, a low forces DO3+ low and DO3- high, and a high forces DO3+ high and DO3- low.
10 DO3+ output Noninverting RS-422 output of transmitter 3.
11 DO3- output Inverting RS-422 output of transmitter 3.
12 EN input Active-low transmitter enable for all four transmitters: drive LOW to enable, HIGH to three-state the outputs; input is hot-swap protected.
13 DO4- output Inverting RS-422 output of transmitter 4.
14 DO4+ output Noninverting RS-422 output of transmitter 4.
15 DI4 input Transmitter 4 input: when transmitter 4 is enabled, a low forces DO4+ low and DO4- high, and a high forces DO4+ high and DO4- low.
16 VCC power_in Positive supply, +3V to +3.6V; bypass VCC to GND with a 0.1µF capacitor.
