20 MBd High CMR Logic Gate Optocouplers

The HCPL-2400 and HCPL-2430 high speed opto-cou- plers combine an 820 nm AlGaAs light Emitting Diode with a high speed photodetector. This combina-tion re- sults in very high data rate capability and low input cur- rent. The totem pole output HCPL-2430 or three state output HCPL-2400 eliminates the need for a pull up re- sistor and allows for direct drive of data buses. The detector has optical receiver input stage with built- in Schmitt trigger to provide Logic compatible wave- forms, eliminating the need for additional waveshaping. The hysteresis provides diferential mode noise immuni- ty and minimizes the potential for output signal chatter. The electrical and switching characteristics of the HCPL- 2400 and HCPL-2430 are guaranteed over the tempera- ture range of 0C to 70C. By Avago Technologies
