DESCRIPTION
The HCPL4503M optocoupler consists 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. The base of the phototransistor is
not bonded out to a pin for improved noise immunity.
An internal noise shield provides superior common mode rejection of 15kV/µs minimum.
FEATURES
• VISO = 5kV RMS is standard for all devices
• High speed-1 MBit/s
• Superior CMR, CM_H = 50 kV/ms (typical); CM_L = 30 kV/ms (typical)
• No base connection for improved noise immunity
• CTR guaranteed 0-70°C
• U.L. recognized (File # E90700, Vol 2)
• VDE approval pending
APPLICATIONS
• Line receivers
• Pulse transformer replacement
• Output interface to CMOS-LSTTL-TTL
• Wide bandwidth analog coupling
