Description
The iC-HE is a three channel line driver with complementary outputs optimized for line impedances in the range of 75. The push-pull output stages can deliver at least 200mA from 24 V supply and are short-circuit-proof and current-limited, shutting down with excessive temperature or undervoltage conditon. All inputs are compatible with CMOS and TTL levels. The emitter and collector outputs of an on-chip NPN transitor is available for driving an external light emitting diode. The base of the transistor is connected to an internal reference voltage of 2.5 V. Collector current at pin LED can be controlled by the value of the resistor connected between ISET and ground. The device is protected against ESD.
