DESCRIPTION
The HCPL-4502/HCPL-2503, 6N135/6 and HCPL-2530/HCPL-2531 optocouplers consist of an AlGaAs LED optically coupled to a
high speed photodetector transistor.
A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional
phototransistor optocouplers by reducing the base-collector capacitance of the input transistor.
An internal noise shield provides superior common mode rejection of 10kV/µs. An improved package allows superior insulation
permitting a 480 V working voltage compared to industry standard of 220 V.
FEATURES
• High speed-1 MBit/s
• Superior CMR-10 kV/µs
• Dual-Channel HCPL-2530/HCPL-2531
• Double working voltage-480V RMS
• CTR guaranteed 0-70°C
•U.L. recognized (File # E90700)
APPLICATIONS
• Line receivers
• Pulse transformer replacement
• Output interface to CMOS-LSTTL-TTL
• Wide bandwidth analog coupling
