3.3V/5V Digital Optocoupler Family

Currently Viewing:

The HCPL-260L optocoupler is an optically coupled gate that combines a GaAsP light emitting diode and an integrated high gain photo detector. An enable input allows the detector to be strobed. 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 kV/ms.

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 degrees C to 85 degrees C allowing trouble-free system performance.

It is suitable for high speed logic interfacing, input/output buffering, as line receivers in environments that conventional line receivers cannot tolerate and are recommended for use in extremely high ground or induced noise environments. It is available in an 8-pin DIP and industry standard SO-8 package.
