Description
Ground, Logic Side.
Logic Side Power Supply. It is recommended that a 0.1 µF and a 10 µF decoupling capacitor be fitted between
Pin 2 and Pin 1.
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.
Logic Side Power Supply. It is recommended that a 0.1 µF and a 0.01 µF decoupling capacitor be fitted between
Pin 8 and Pin 9.
Ground, Logic Side.
Ground, Logic Side.
Ground, Bus Side.
Isolated Power Supply Output. This pin must be connected externally to V
capacitor of 10 µF and a decoupling capacitor of 0.1 µF be fitted between Pin 12 and Pin 11.
