Description

H= High Level, L= Low Level,

X= Irrelevant, Z= High Impedance

The IL485-3V is a galvanically isolated, high speed differential

bus transceiver, designed for bidirectional data communication

on balanced transmission lines. Isolation is achieved through

patented Isoloop technology. The IL485-3V is the first isolated

IL485-3V

Standard 3V Part Number

RS-485 interface available in a standard 16 pin SOIC package,

which meets the ANSI Standards EIA/TIA-422-B and RS485 and

is compatible with 3.3V input supplies.

IL485E-3VTR Lead Free/Tape and Reel

The IL485-3V has current limiting and thermal shutdown

features to protect against output short circuits and bus

contention situations where these may cause excessive power

dissipation.

With 1 nsec pulse skew and 16 nsec propagation delay, the IL485

is ideal for PROFIBUS applications.
