±60V Fault Protected RS-485/RS-422
level I/O pin. On the ISL31480E, or 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.

N/A
±60V Fault 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

N/A
±60V Fault 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.

N/A
±60V Fault 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

N/A
±60V Fault 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

System power supply input (4.5V to 5.5V).
VL

N/A
12

14
Logic-Level Supply input (1.62V to VCC)
which powers all the TTL/CMOS inputs and
the RO output (logic pins). VL sets the VIH
and VIL levels for logic input pins, and sets
the VOH level for the RO pin. Power up this
supply after VCC, and keep VL ≤ VCC. To
minimize input current, logic input pins that
are strapped high externally should connect
to VL, but they may be connected to VCC if
necessary.
INV
N/A
2
3
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
N/A
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

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.
