Low Power 1 MBd Digital Optocoupler

The Avago ACPL-M50L (single-channel, SO-5 package) is a low power, low input current, open-collector output digital optocoupler.

ACPL-M50L uses an insulating layer between the light emitting diode and an integrated photon detector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increase the speed up to a hundred times over that of a conventional photo-transistor coupler by reducing the base collector capacitance.

ACPL-M50L has an increased common mode transient immunity of 15kV/µs minimum at V_CM = 1500V over a temperature range of -40°C to 105°C. The current transfer ratio (CTR) is 140% typical at I_F = 3mA. This digital optocoupler can be used in any  TTL/CMOS, TTL/LSTTL or wide bandwidth analog applications.
