The Broadcom ACPL-247-560E is a Phototx optocoupler quad with transistor output, designed to provide an optically isolated barrier between two circuits. With a transistor output option, the unit offers open-collector output to sink current, allowing for higher power dissipation than traditional optocouplers. It has a quiescent current of 2.4 mA, and the phototransistor supply voltage is 5V. The device has an input-output isolation of 5000 Vrms, and an isolation resistance of 1012 ohms at 500 VDC. The coupling capacitance is 850pF typical, and the minimum input-trigger current is 0.3mA. The performance of the device is up to 1Mbaud in digital transmission systems, and it is also used for high speed analogue signal transferACPL-247-560E has a reliable electrical performance, and a high common mode transient immunity of greater than 25KV/us. It is suitable for industrial applications such as motor control, factory automation, process control, and building/home automation systems.
