High Speed LVTTL Compatible 3.3/5 Volt Optocouplers

Currently Viewing:

The ACPL-W60L/K63L are LVTTL/LVCMOS compatible optocoupler gates that combine a GaAsP 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 15kV/μs.

This unique design provides maximum AC and DC circuit isolation while achieving LVTTL/LVCMOS compatibility. The optocoupler AC and DC operational parameters are guaranteed from –40°C to 85°C allowing trouble-free system performance.
