The HCPL-261N family allows direct interface to all common circuit topologies without additional LED buffer or drive components. The AlGaAs LED used allows lower drive currents and reduces degradation by using the latest LED technology. On the single channel parts, an enable output allows the detector to be strobed. The output of the detector IC is an open collector schottky-clamped transistor. The internal shield provides a minimum common mode transient immunity of 15000 V/µs for the HCPL-261N family.
