HCMOS Compatible, High CMR, 10 MBd Optocouplers

Currently Viewing:

The HCPL-263A family of optically coupled gates provide all the benefits of the industry standard 6N137 family with the added benefit of HCMOS compatible input current. This 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 1 kV/µs for the HCPL-263A family and 15 kV/µs for the HCPL-263N family.
