NOTES:
1. 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.
2. Please refer to TB347 for details on reel specifications.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL3282EMRTEP. For more information on MSL please see techbrief
TB363.

Pin Descriptions
PIN NAME
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. If the Rx enable function isn’t used, connect
RE directly to GND. RE is internally pulled high.
GND Ground connection. This is also the potential of the TDFN thermal pad.
A
±16.5kV IEC61000 ESD Protected RS-485, RS-422 level, noninverting receiver input.
B
±16.5kV IEC61000 ESD Protected RS-485, RS-422 level, inverting receiver input.
V_CC
System power supply input (3.0V to 5.5V). On devices with a V_L pin, power-up V_CC first.
V_L
Logic-Level Supply which sets the V_IL/V_IH levels for the RE pin, and sets the V_OH level of the RO output. Power-up this supply after V_CC, and
keep V_L ≤ V_CC.
NC
No Connection.
