ESM1602B

ESM1602B QUAD COMPARATOR INTERFACE CIRCUIT . . . . . 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 PROTECTION DIODES. DIP14 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. The ESM1602B 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. PIN CONNECTIONS (top view) DIP14 SO16 SO16 ORDER ING NUMBERS: ESM1602B (DIP14) ESM1602BFP (SO16) The ESM1602B can operate in a wide supply voltage 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. 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 ...
