The Broadcom® 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 an open collector
Schottky-clamped transistor. The internal shield provides a
guaranteed common mode transient immunity specification
up to 15,000 V/μs at Vcm = 1000V.
This unique design provides maximum AC and DC circuit
isolation while achieving TTL compatibility. The optocoupler
AC and DC operational parameters are guaranteed from –
40°C to +85°C allowing trouble-free system performance.
