3.3V/5V High Speed Digital CMOS Optocoupler

Currently Viewing:

The single-channel ACPL-M75L  is a 15 MBd CMOS optocoupler in a SOIC-5 package. The  optocouplers utilize the latest CMOS IC technology to achieve outstanding performance with very low power consumption.

Basic building blocks of ACPL-M75L are high speed LEDs and CMOS detector ICs. Each detector incorporates an integrated photodiode, a high speed transimpedance amplifier, and a voltage comparator with an output driver.
