The Broadcom ACSL-6400-50TE with Optocoupler Logic-Out Open Collector DC-IN 4-CH 16-Pin SOIC N T/R is a four-channel integrated optically isolated digital output device. It consists of an open collector optocoupler, which provides an isolated logic-level output, and integrated high side switch drivers. The device operates from DC supply voltage ranges from 4V to 50V, hence the suffix "-50TE". The device has a 16-Pin SOICN package type, and is supplied in tapes and reels for use with automated pick-and-place equipment. The device uses an open-collector structure with TTL compatible output voltages, and is ideal for transmitting signals across the isolation barrier. The device can drive up to 400mA loads for each channel, making it suitable for driving LEDs, relays, and other loads in industrial applications.
