DESCRIPTION
The ESM1600Bis a quadruplecomparatorintented to provide an interface between signal processing and transmitting lines in very noisy industrial surroundings.
Outputof eachcomparator,used asline driver, supplies a constant current (PNP output stage) and is specially well protected against powerful overvoltages. The open collector output circuit allows the connectionof several comparatorsto a single transmitting 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.
. MINIMUM HYSTERESIS VOLTAGE AT EACH INPUT : 0.3V
. OUTPUT CURRENT : 15 mA
. LARGE SUPPLY VOLTAGE RANGE : + 10V to + 35V
. INTERNAL THERMAL PROTECTION
. INPUT AND OUTPUT CLAMPING PROTEC TION DIODES.
