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 V
CC
and be connected to ISO DE IN for
normal operation (Table 1 of Figure 2).

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 V
CC
and be connected to ISO DI IN for normal operation (Table 1 of Figure 2).
