Description
The 6N137, HCPL-26XX/06XX/
4661, HCNW137/26X1 are
optically coupled gates that
combine a GaAsP light emitting
diode and an integrated high gain
photo detector. An enable input
allows the detector to be strobed.
The output of the detector IC is
• Pulse Transformer
Replacement
• Strobable Output (Single
Channel Products Only)
• Safety Approval
