Function
Ground, Logic Side.
Power Supply. Decoupling capacitor to GND
Ground, Logic Side.
Receiver Output Data. This output is high when (A – B) > 200 mV and low when (A – B) < –200 mV. The
output is tristated when the receiver is disabled, that is, when RE is driven high.
Receiver Enable Input. This is an active-low input. Driving this input low enables the receiver; driving it high
disables the receiver.
Driver Enable Input. Driving this input high enables the driver; driving it low disables the driver.
Driver Input. Data to be transmitted by the driver is applied to this input.
Power Supply. Decoupling capacitor to GND
Ground, Logic Side.
Ground, Logic Side.
Ground, Bus Side.
Isolated Power Supply Output. This pin must be connected externally to V
Driver Non-inverting output
Ground (bus side).
Driver Inverting output
Ground (bus side).
Receiver Inverting Input.
Receiver Non-inverting Input.
Isolated Power Supply Input. This pin must be connected externally to V
