■ Data multiplexing

■ Switching power supplies

■ Pulse transformer replacement

■ Computer-peripheral interface

Description

These optocouplers consist of an AlGaAS LED, optically

coupled to a very high speed integrated photo-detector

logic gate. Devices include a strobable output. This

output features an open collector, thereby permitting

wired

OR

outputs. The

coupled

parameters

are

guaranteed over the temperature range of -40°C to

+85°C. A maximum input signal of 5 mA will provide a

minimum output sink current of 13 mA (fan out of 8). An

internal noise shield provides superior common mode

rejection of typically 50 kV/µs at 1,000V common mode.
