6N138,6N139
TOSHIBA Photocoupler
GaAℓAs Ired & Photo IC
6N138, 6N139
Current Loop Driver.
Low Input Current Line Receiver.
CMOS Logic Interface.
The TOSHIBA 6N138 and 6N139 consists of a GaAℓAs
infrared
emitting diode coupled with a split-Darlington output
configuration.
A high speed GaAℓAs Ired manufactured with an unique
LPE junction, has the virtue of fast rise and fall time at
low drive current.
