NOTES:
1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte
tin plate PLUS ANNEAL - e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations.
Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC
J STD-020.

FUNCTION
RO
Receiver output: If A - B ≥ -50mV, RO is high; If A - B ≤ -200mV, RO is low; RO = High if A and B are unconnected (floating)
or shorted.
RE
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high.
DE
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when DE is
low.
DI
Driver input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low.
GND
Ground connection.
A/Y
±15kV HBM ESD Protected RS-485/RS-422 level, noninverting receiver input and noninverting driver output. Pin is an input
if DE = 0; pin is an output if DE = 1.
B/Z
±15kV HBM ESD Protected RS-485/RS-422 level, Inverting receiver input and inverting driver output. Pin is an input if DE
= 0; pin is an output if DE = 1.
A
±15kV HBM ESD Protected RS-485/RS-422 level, noninverting receiver input.
B
±15kV HBM ESD Protected RS-485/RS-422 level, inverting receiver input.
Y
±15kV HBM ESD Protected RS-485/RS-422 level, noninverting driver output.
Z
±15kV HBM ESD Protected RS-485/RS-422 level, inverting driver output.
V_CC
System power supply input (4.5V to 5.5V).
NC
No Connection.
