Pin Description
PIN
NAME
ISOLATION SIDE
FUNCTION
1VCC1
Logic
Logic-Side/Transformer-Driver Power Input. Bypass VCC1 to GND1 with 10F and 0.1F
capacitors.
2
ST1
Logic
Transformer-Driver Phase 1 Power Output. Connect ST1 to isolation-transformer
primary to send power to isolation side of barrier.
3
ST2
Logic
Transformer-Driver Phase 2 Power Output. Connect ST2 to isolation-transformer
primary to send power to isolation side of barrier.
4
GND1
Logic
Logic-Side Ground. For isolated operation do not connect to GND2.

11
GND2
Isolated
Isolation-Side Ground. For isolated operation do not connect to GND1.
12
Z
Isolated
RS-485/RS-422 Inverting Driver Output. Output floats when DE is low or in a barrier fault
event. (See the Detailed Description section for more information.)
13
Y
Isolated
RS-485/RS-422 Noninverting Driver Output. Output floats when DE is low or in a barrier
fault event. (See the Detailed Description section for more information.)
14
VCC2
Isolated
Isolated-Side Power Input. Connect VCC2 to the rectified output of transformer
secondary. Bypass VCC2 to GND2 with 10F and 0.1F capacitors.
15
B
Isolated
RS-485/RS-422 Differential-Receiver Inverting Input
16
A
Isolated
RS-485/RS-422 Differential-Receiver Noninverting Input
17
RO2
Isolated
Isolated-Side Receiver Output. RO2 is always enabled. RO2 goes high if A - B > -10mV.
RO2 goes low if A - B < -200mV. Fail-safe circuitry causes RO2 to go high when A and B
float or are shorted.
18
SLO
Isolated
Driver Slew-Rate Control Logic Input. Connect SLO to GND2 for data rates up to
400kbps. Connect SLO to VCC2 or leave floating for high data rates.
25
DI
Logic
Driver Input. Pull DI low (high) to force driver output Y low (high) and driver output Z
high (low).
26
DE
Logic
Driver-Enable Input. The driver outputs are enabled and follow the driver input (DI)
when DE is high. When DE is floated, the driver is disabled. DE does not affect whether
the receiver is on or off.
27
RE
Logic
Receiver-Output Enable and Fault Current Output. The receiver output (RO1) is
enabled and follows the differential-receiver inputs, A and B, when RE is low, otherwise
RO1 floats. RE does not affect RO2 and does not disable the driver. The asserted fault
output is a pullup current, otherwise RE shows a pulldown current.
28
RO1
Logic
Receiver Output. RO1 is enabled when RE is low. RO1 goes high if A - B > -10mV. RO1
goes low if A - B < -200mV. Fail-safe circuitry causes RO1 to go high when A and B
float or are shorted.
