______________________________________________________________Pin Description
Driver Input. 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. Drives internal LED cathode through R1 (Table 1 of Figure 2).
DI

Logic-Side (non-isolated side) +3.3V Supply Voltage Input. Connect to pins 1, 2, and 14.
VCC4
10
Boosted V+ Voltage Input. Must be connected as shown in Figures 1 and 2.
VCC3

Frequency Switch Input. If FS = VCC, switch frequency is high; if FS = 0V, switch frequency is low
(normal connection).

FUNCTION
NAME
Driver-Enable 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. Drives
internal LED cathode through R2 (Table 1 of Figure 2).
DE
11
Receiver Output. If A > B by 200mV, RO will be low; if A < B by 200mV, RO will be high. Open collector;
must have pull-up (R3) to VCC (Table 1 of Figure 2).
RO
13
Logic-Side (non-isolated side) +3.3V Supply Voltage Input. Connect to pins 1, 2, and 10.
VCC5
14
Power-Supply Shutdown Input. Must be connected to logic ground.
