Mnemonic
Function
1
D1
Transformer Driver Terminal 1.
2
D2
Transformer Driver Terminal 2.
3
GND1
Ground, Logic Side.
4
VDD1
Power Supply, Logic Side (3.3 V or 5 V). Decoupling capacitor to GND1 required; capacitor value should be
between 0.01 μF and 0.1 μF.
5
RxD
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.
6
RE
Receiver Enable Input. This is an active-low input. Driving this input low enables the receiver; driving it
high disables the receiver.
7
RTS
Driver Enable Input. Driving this input high enables the driver; driving it low disables the driver.
8
TxD
Driver Input. Data to be transmitted by the driver is applied to this input.
9, 11, 14, 15
GND2
Ground, Bus Side.
10
DE OUT
Driver Enable Status Output.
12
A
Noninverting Driver Output/Receiver Input. When the driver is disabled or VDD1 or VDD2 is powered down,
Pin A is put in a high impedance state to avoid overloading the bus.
13
B
Inverting Driver Output/Receiver Input. When the driver is disabled or VDD1 or VDD2 is powered down,
Pin B is put in a high impedance state to avoid overloading the bus.
16
VDD2
Power Supply, Bus Side (Isolated 5 V Supply). Decoupling capacitor to GND2 required; capacitor value
should be between 0.01 μF and 0.1 μF.
