ESM1602B
ESM1602B is QUAD COMPARATOR INTERFACE CIRCUIT manufactured by STMicroelectronics.
DESCRIPTION
The ESM1602Bis a quadrupleparatorintented to provide an interface between signal processing and transmitting lines in very noisy industrial surroundings. Outputof each parator,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 parators 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 parator provides an excellent noise immunity. In addition, each input is also protected against overvoltages.

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 paratorswhen power dissipation bees excessive.
