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.
