HCPL-2400 General Description
The HCPL-2400 and HCPL-2430 high speed optocouplers combine an 820 nm AlGaAs light emitting diode with a high speed photodetector. This combination 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.
