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 photodetector 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 rejection 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
