DESCRIPTION
The ESM1600Bis a quadruplecomparatorintented
to provide an interface between signal processing
and transmitting lines in very noisy industrial sur-
roundings.
Outputof each comparator,used as line driver, sup-
plies a constant current (PNP output stage) and is
specially well protected against powerful overvol-
tages. The open collector output circuit allows the
connectionof several comparators to a single trans-
mitting line.
The ESM1600B can operate as receiver on a line
transmitting noisy high-voltage signals. Hysteresis
effect, internally implemented on inputs of each
comparator provides an excellent noise immunity.
In addition, each input is also protected against
overvoltages.

The ESM1600B can operate in a wide supply vol-
tage range (standard operational amplifier ± 15 V
supply or single + 12 V or + 24 V supplies used in
industrial electronic sets).
Moreover, internal thermal protection circuitry cuts
out the output current of the four comparatorswhen
power dissipation becomes excessive.
