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.
