The push-pull output stages can deliver at least 200 mA from 24 V supply and are short-circuit-proof and current-limited, shutting down with excessive temperature or undervoltage conditon. 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. All inputs are compatible with CMOS and TTL levels.

Absolute Maximum Ratings are no Operating Conditions. Integrated circuits with system interfaces, e.g. via cable accessible pins (I/O pins, line drivers) are per principle endangered by injected interferences, which may compromise the function or durability. The robustness of the devices has to be verified by the user during system development with regards to applying standards and ensured where necessary by additional protective circuitry. By the manufacturer suggested protective circuitry is for information only and given without responsibility and has to be verified within the actual system with respect to actual interferences.
