FUNCTION
RO
2
1
Receiver output. If INV or RINV is low, then: If A - B
≥ -10mV, RO is high; if A - B ≤ -200mV, RO is low. If INV or
RINV is high, then: If B - A
≥ -10mV, RO is high; if B - A ≤ -200mV, RO is low. In all cases, RO = High if A and B
are unconnected (floating), or shorted together, or connected to an undriven, terminated bus (i.e., Rx is always
failsafe open, shorted, and idle, even if polarity is inverted).
RE
3
N/A
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. Internally
pulled low.
DE
4
3
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high, and they are high
impedance when DE is low. Internally pulled high to VCC.
DI
5
4
Driver input. If INV or DINV is low, a low on DI forces output Y low and output Z high, while a high on DI forces
output Y high and output Z low. The output states relative to DI invert if INV or DINV is high.
GND
6, 7
5
Ground connection.
A/Y
N/A
6
±60V Fault and ±16.5kV HBM ESD Protected RS-485/RS-422 level I/O pin. If INV is low, A/Y is the
non-inverting receiver input and non-inverting driver output. If INV is high, A/Y is the inverting receiver input
and the inverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1.
B/Z
N/A
7
±60V Fault and ±16.5kV HBM ESD Protected RS-485/RS-422 level I/O pin. If INV is low, B/Z is the inverting
receiver input and inverting driver output. If INV is high, B/Z is the non-inverting receiver input and the
non-inverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1.
A
12
N/A
±60V Fault and ±15kV HBM ESD Protected RS-485/RS-422 level input. If RINV is low, then A is the
non-inverting receiver input. If RINV is high, then A is the inverting receiver input.
B
11
N/A
±60V Fault and ±15kV HBM ESD Protected RS-485/RS-422 level input. If RINV is low, then B is the inverting
receiver input. If RINV is high, then B is the non-inverting receiver input.
Y
9
N/A
±60V Fault and ±15kV HBM ESD Protected RS-485/RS-422 level output. If DINV is low, then Y is the
non-inverting driver output. If DINV is high, then Y is the inverting driver output
Z
10
N/A
±60V Fault and ±15kV HBM ESD Protected RS-485/RS-422 level. If DINV is low, then Z is the inverting driver
output. If DINV is high, then Z is the non-inverting driver output
VCC
13, 14
8
System power supply input (4.5V to 5.5V).
INV
N/A
2
Receiver and driver polarity selection input. When driven high, this pin swaps the polarity of the driver output
and receiver input pins. If unconnected (floating) or connected low, normal RS-485 polarity conventions
apply. Internally pulled low.
RINV
1
N/A
Receiver polarity selection input. When driven high, this pin swaps the polarity of the receiver input pins. If
unconnected (floating) or connected low, normal RS-485 polarity conventions apply. Internally pulled low.
DINV
8
N/A
Driver polarity selection input. When driven high, this pin swaps the polarity of the driver output pins. If
unconnected (floating) or connected low, normal RS-485 polarity conventions apply. Internally pulled low.
