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.

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

NC

No Connection.
