Description
Features
The HCPL-2400 and HCPL-2430 high speed opto-couplers combine an 820 nm AlGaAs light emitting diode
with a high speed photodetector. This combina-tion results in very high data rate capability and low input current. The totem pole output (HCPL-2430) or three state
output (HCPL-2400) eliminates the need for a pull up resistor and allows for direct drive of data buses.
• High speed: 40 MBd typical data rate
The detector has optical receiver input stage with builtin Schmitt trigger to provide logic compatible waveforms, eliminating the need for additional waveshaping.
The hysteresis provides differential mode noise immunity and minimizes the potential for output signal chatter.
The electrical and switching characteristics of the HCPL2400 and HCPL-2430 are guaranteed over the temperature range of 0°C to 70°C.
