Quad Differential Line Driver, Pin-Compatible with xx2068
iC-HD2 is a robust line driver for industrial 5 V and 24 V applications with four complementary output channels. 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. VREF acts as a 5 V voltage supply for external loads of up to 5 mA.
