Description
Features
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.
•
•
High speed: 40 MBd typical data rate
High common mode rejection:
HCPL-2400: 10 kV/µs at VCM = 300 V (typical)
•
•
•
AC performance guaranteed over temperature
High speed AlGaAs emitter
Compatible with TTL, STTL, LSTTL, and HCMOS logic
families
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 differential mode noise immuni-
ty and minimizes the potential for output signal chatter.

•
Totem pole and tri state output (no pull up resistor
required)
Safety approval
