Description
1
VDD1
Power Supply (Logic Side). Decoupling capacitor to GND1 required; capacitor value should be between 0.01 F and 0.1 F.
2
GND1
Ground (Logic Side).
3
RxD
Receiver Output.
4
RE
Receiver Enable Input. Active low logic input. When this pin is low, the receiver is enabled; when this pin is high, the
receiver is disabled.
5
DE
Driver Enable Input. Active high logic input. When this pin is high, the driver (transmitter) is enabled; when this pin
is low, the driver is disabled.
6
TxD
Transmit Data.
7
NC
No Connect. This pin must be left floating.
8
GND1
Ground (Logic Side).
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). Decoupling capacitor to GND2 required; capacitor value should be between 0.01 F and 0.1 F.
