Description
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
DE
Driver Enable Input. Driving this input high enables the driver; driving it low disables the driver.
8
TxD
Transmit Data.
9
GND2
Ground, Bus Side.
10
NC
No Connect. This pin must be left floating.
11
Y
Driver Noninverting Output.
12
Z
Driver Inverting Output.
13
B
Receiver Inverting Input.
14
A
Receiver Noninverting Input.
15
GND2
Ground, Bus Side.
16
VDD2
Power Supply, Bus Side (Isolated 3.3 V Supply). Decoupling capacitor to GND2 required; capacitor value should be
between 0.01 μF and 0.1 μF.
