DESCRIPTION
The ESM1602Bis a quadruplecomparatorintented to provide an interface between signal processing and transmitting lines in very noisy industrial surroundings. Outputof each comparator,used as line 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 comparators to a single transmitting line. Hysteresis effect, internally implemented on inputs of each comparator provides an excellent noise immunity. In addition, each input is also protected against overvoltages. Moreover, internal thermal protection circuitry cuts out the output current of the four comparatorswhen power dissipation becomes excessive. 1 - Inverting input 1 2 - Non-inverting input 3 - Output 1 4 - Non-inverting input 5 - Inverting input 2 6 - Output 2 7 - GND 8 - Output 3 9 - Inverting input 3 10 - Non-inverting input 11 - Output 4 12 - Non-inverting input 13 - Inverting input 4 14 - VCC 1 2 3 4 1 - Inverting input 1 2 -Non-inverting input 1 3 - Output 1 4 - Non-inverting input 2 5 - Inverting input 2 6 - Output 2 7 - GND 8 - N.C.
