Package
Description
The 6N137, HCPL-2601/2611 single-channel and HCPL-2630/
2631 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 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 13mA (fan out of 8).
An internal noise shield provides superior common mode rejec-
tion of typically 10kV/µs. The HCPL- 2601 and HCPL- 2631 has
a minimum CMR of 5 kV/µs. The HCPL-2611 has a minimum
CMR of 10 kV/µs.
