Low Input Current Logic Gate Optocouplers

Currently Viewing:

The HCPL-2200 optocoupler  is an optically coupled logic gate that combines a GaAsP LED and an integrated high gain photodetector. The detector has a three state output stage and has a detector threshold with hysteresis. The three state output eliminates the need for a pullup resistor and allows for direct drive of data busses. The hysteresis provides differential mode noise immunity and eliminates the potential for output signal chatter.

The Electrical Switching Characteristics of the HCPL-2200 are guaranteed over the temperature range of 0 degrees C to 85 degrees C and a VCC range of 4.5 volts to 20 volts. Low IF and wide VCC range allow compatibility with TTL, LSTTL, and CMOS logic and result in lower power consumption compared to other high speed optocouplers. Logic signals are transmitted with a typical propagation delay of 160 nsec.

It is useful for isolating high speed logic interfaces, buffering of input and output lines, and implementing isolated line receivers in high noise environments.
