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.
• Isolation voltage: 2500Vrms (min.)
• Current transfer ratio
: 6N138 − 300% (min.) (I_F=1.6mA)
: 6N139 − 400% (min.) (I_F=0.5mA)
• Switching time: 6N138 − t_PHL=10μs (max.)
− t_PLH=35μs (max.)
6N139 − t_PHL=1μs (max.)
− t_PLH=7μs (max.)
