Description

The ACPL-071L (single-channel) and ACPL-074L (dual-

channel) are 15 MBd CMOS optocouplers in SOIC-8 pack-

age. The optocouplers utilize the latest CMOS IC technol-

ogy to achieve outstanding performance with very low

power consumption. Basic building blocks of ACPL-071L

and ACPL-074L 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.

Applications

• Digital field bus isolation:

• CANBus, RS485, USB

• Multiplexed data transmission

• Computer peripheral interface

• Microprocessor system interface

• DC/DC converter
