The ICPL 2611 consists of a GaAsP emitting diode and a unique integrated detector. The photons are detected by a photodiode and then amplified by a high gain linear amplifier that drives a logic gate with a strobable output. This output features a Schottky clamped open collector output transistor. The circuit is temperature, current and voltage compensated. This unique isolator design provides maximum DC and AC circuit isolation between input and output while achieving LSTTL/TTL circuit compatibility. The isolator operational parameters are guaranteed from 0C to 70C, such that a minimum input current of 5 mA will sink an eight gate fan-out (13mA) at the output with 5 volt Vcc supplied to the detector. This isolation and coupling is achieved with a typical propagation delay of 39ns. The enable input provides gating of the detector with input sinking and sourcing requirements compatible with LSTTL/TTL interfacing and a propagation delay of 35ns typical.
