HCPL4503M

The HCPL4503M is a 1-channel 8-pin high speed Transistor Optocoupler consists of an AlGaAs LED optically coupled to a high speed photodetector transistor for each channel. A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional phototransistor optocoupler by reducing the base-collector capacitance of the input transistor. It is suitable for line receivers, pulse transformer replacement, output interface to CMOS-LSTTL-TTL and wide-bandwidth analogue coupling. It has no internal connection to the phototransistor base for improved noise immunity. An internal noise shield provides superior common-mode rejection of up to 50000V/μs.

• 1Mbps High speed
