Data Sheet
Description
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 dierential 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 0°C to 70°C.
