NAME
ISOLATION SIDE
FUNCTION
1
V
CC1
Logic
Logic-Side/Transformer-Driver Power Input. Bypass V
CC1
to GND1 with 10μF and 0.1μF
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.

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
V
CC2
Isolated
Isolated-Side Power Input. Connect V
CC2
to the rectified output of transformer
secondary. Bypass V
CC2
to GND2 with 10μF and 0.1μF capacitors.

SLO
Isolated
Driver Slew-Rate Control Logic Input. Connect
SLO
to GND2 for data rates up to
400kbps. Connect
SLO
to V
CC2
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.
