H = High Level
The IL485W has current limiting and thermal shutdown features to
protect against output short circuits and bus contention situations where
these may cause excessive power dissipation.
L = Low Level
X = Irrelevant
With a 1 nsec pulse skew and 16 nsec propagation delay, the IL485W is
ideal for PROFIBUS applications. Use of DE/ISODE and IN1/OUT1
allows the IL485W to perform the handshaking operations of RTSAS
and DTSAS of PROFIBUS.
Z = High Impedance
