10MBd Wide Operating Temperature Automotive Digital Optocoupler with R²Coupler™ Isolation and AEC-Q100 Qualification

Currently Viewing:

The ACPL-M61T, AEC-Q100 compliant, optically coupled gates combine an AlGaAs light emitting diode and an integrated high gain photo detector.

The output of the detector IC is an Open-collector Schottky-clamped transistor. The internal shield provides a guaranteed common mode transient immunity specification of 15,000 V/µs at VCM=1000V.

This small outline wide operating temperature, high CMR, high speed, logic gate optocoupler is a single channel device in a five lead miniature footprint.

This optocoupler is suitable for use in automotive high speed communications logic interfacing with low propagation delays, input/output buffering and is recommended for use in high operating temperature environment.

This unique design provides maximum AC and DC circuit isolation while achieving TTL compatibility. The optocoupler AC and DC operational parameters are guaranteed from -40°C to 125°C.
