Pin No. Mnemonic Description
1
GND1
Ground, Logic Side.
2
VCC
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.
3
GND1
Ground, Logic Side.
4
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.
5
RE
Receiver Enable Input. This is an active-low input. Driving this input low enables the receiver; driving it
high disables the receiver.
6
DE
Driver Enable Input. Driving this input high enables the driver; driving it low disables the driver.
7
TxD
Driver Input. Data to be transmitted by the driver is applied to this input.
8
VCC
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 7.
9

Ground, Logic Side.
Ground, Bus Side.
12
VISOOUT
Isolated Power Supply Output. This pin must be connected externally to VISOIN. It is recommended that a reservoir
capacitor of 10 μF and a decoupling capacitor of 0.1 μF be fitted between Pin 12 and Pin 11.

Receiver Noninverting Input.
19
VISOIN
Isolated Power Supply Input. This pin must be connected externally to VISOOUT. It is recommended that a
0.1 μF and a 0.01 μF decoupling capacitor be fitted between Pin 19 and Pin 20.
20
GND2
Ground, Bus Side.
