3.3V/5V High Speed Digital CMOS Optocoupler

Currently Viewing:

The ACPL-071L single-channel, 15MBd CMOS optocouplers utilize the latest CMOS IC technology to achieve outstanding performance with very low power consumption.

The building blocks of the 3.3V/5V ACPL-071L optocouplers 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.

ACPL-071L optocouplers are available in  SOIC-8 packages.
