_________________________________________________Pin Description (continued)
Isolated Driver-Enable Drive Input. The driver outputs, A and B, are enabled by bringing DE
high.
The driver outputs are high impedance when DE
is low. If the driver outputs are enabled, the device
functions as a line driver. While the driver outputs are high impedance, the device functions as a line
receiver. Open collector output; must have pull-up (R4) to ISO VCC and be connected to ISO DE IN for
normal operation (Table 1 of Figure 2).

NAME
Isolated-Supply Positive Input Voltage. Connect to ISO VCC1.
ISO VCC2
18
Isolated Driver-Input Drive. With DE
high, a low on DI forces output A low and output B high. Similarly,
a high on DI
forces output A high and output B low. Open-collector output; must have pull-up (R5) to
ISO VCC and be connected to ISO DI IN for normal operation (Table 1 of Figure 2).

Isolated-Supply Common Output. Connect to ISO COM2. If RS-485 wires have a shield, connect ISO
COM1 to shield via 100
resistor.

Isolated Receiver-Output LED Anode (input). If A > B by 200mV, ISO RO LED will be high; if A < B by
200mV, ISO RO LED will be low.
