Description
The 6N137, HCPL2601, HCPL2611 single-channel and
HCPL2630, HCPL2631 dual-channel optocouplers
consist of a 850 nm AlGaAS LED, optically coupled to a
very high speed integrated photo-detector logic gate with
a strobable output. This output features an open collec-
tor, 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 5mA will
provide a minimum output sink current of 13mA (fan out
of 8).
An internal noise shield provides superior common
mode rejection of typically 10kV/µs. The HCPL2601 and
HCPL2631 has a minimum CMR of 5kV/µs. The
HCPL2611 has a minimum CMR of 10kV/µs.
