Digital Optocoupler Conserves Drive Current

Reportedly operating on 80% less drive current than standard 1-MBd devices, the ACPL-M50L single-channel optocoupler assumes position as the industry’s most efficient. It operates on supply voltages from 2.7V to 24V with a forward drive current of 3 mA and higher. Other specs include a current transfer ratio greater than 80%, an operating temperature range from -40°C to +105°C, open-collector output, TTL compatibility, a 15-kV/µs CMR at Vcm = 1.5 kV, and a propagation delay of 1 ms maximum. Price for the ACPL-M50L starts at $0.75 each/2,500. AVAGO TECHNOLOGIES, San Jose, CA. (877) 673-9442.
