iC-HD7 is a robust line driver for industrial 5 V and 24 V applications with four complementary output channels. For signal lines with a characteristic impendance of 30 to 140 the integrated line adapter, optimized to 75, minimizes ringing effectrs which arise when there is no line termination.
At a supply of 24 V the push-pull driver stages typically provide 200 mA to discharge the line and also have a low saturation voltage (of typically 200 mV with a 40 mA low-side load). The outputs are current limited and short-circuit-proof, shutting down with excessive temperature. For bus applications the driver stages can be switched to high impedance by a high at input NEN.
The driver stage inputs have a Schmitt trigger characteristic and are compatible with CMOS and TTL levels. For test purposes the temperature monitor can be deactivated by applying a voltage of greater than 12 V to input NEN.
The device contains internal ESD protection circuitry.
