The ACSL-6xx0 series optocouplers feature the GaAsP

LEDs with proprietary back emission design. They offer

the designer a broad range of input drive current, from

7 mA to 15 mA, thus providing greater flexibility in

designing the drive circuit.

The output detector integrated circuit (IC) in the opto-

coupler consists of a photodiode at the input of a two-

stage amplifier that provides both high gain and high

bandwidth. The secondary amplifier stage of the detector

IC feeds into an open collector Schottky-clamped transis-

tor.

The entire output circuit is electrically shielded so that any

common-mode transient capacitively coupled from the LED

side of the optocoupler is diverted from the photodiode

to ground. With this electric shield, the optocoupler can

withstand transients that slopes up to 10,000V/µs, and am-

plitudes up to 1,000V.
