1. Description

The HCPL-063L-500E are optically coupled gates that combine 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/µs at 3.3V. This unique design provides maximum AC and DC circuit isolation while achieving LVTTL/LVCMOS compati-bility. The optocoupler AC and DC operational parameters are guaranteed from –40 °C to +85 °C allowing troublefree system performance. These optocouplers are 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.
