HIGH SPEED-10 MBit/s
LOGIC GATE OPTOCOUPLERS
SINGLE-CHANNEL
6N137
HCPL-2601
HCPL-2611
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 13
mA (fan out of 8).
An internal noise shield provides superior common mode rejection of typically 10
kV/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.
