High-speed 8-pin logic gate optocoupler for industrial buses

September 15, 2015 // By Graham Prophet
Everlight Electronics adds a new high-speed 8-Pin SOP logic gate optocoupler, rated at 15Mbps, with 3.3V and 5V CMOS compatibility, high CMR, and high isolation voltage.

LED and optoelectronics device maker (Taiwan) aims the device at industrial applications. The EL071L consists of an infrared emitting diode optically coupled to a CMOS detector IC. An SMD device, it is packaged in a small outline 8-pin SOP. Data transmission rate is 15Mbps suiting the EL071L for serial and field bus interface isolation in industrial applications, including data transmission for line receivers, data multiplexing, switching power supplies, pulse transformer replacement, computer peripheral interface and high speed logic ground isolation.

Features include both 3.3V and 5V CMOS compatibility, and 10 kV/ µsec minimum common mode transient immunity. Operation is over -40 to 110°C, and the EL071L also features isolation voltage between input and output of 3,750 Vrms.
