6N138, 6N139

HIGH SPEED OPTICALLY

COUPLED ISOLATOR

PHOTODARLINGTON OUTPUT

APPROVALS

l UL recognised, File No. E91231

DESCRIPTION

These diode-darlington optocouplers use a light
emitting diode and an integrated high gain photon
detector to provide 2500Volts
between input and output. Seperate connection for

electrical isolation

RMS

the photodiode bias and output darlington collector
improve the speed up to a hundred times that of a
conventional photo-darlington coupler by reducing
the base-collector capacitance.

FEATURES

l High speed - DC to 300kBits/s operation

l High Common Mode Transient

Immunity 10kV/µs typical

l TTL Compatible - 0.1V V

l Base access allows Gain Bandwidth

typical

OL

Adjustment

l Low Input Current Requirement - 0.5mA

l High Current Transfer Ratio - 2000% typ.

l Open Collector Output

l 2500V

l 6N139 has improved noise shield which

Withstand Test Voltage, 1 min

RMS

gives superior common mode rejection

l Options :-

10mm lead spread - add G after part no.
Surface mount - add SM after part no.
Tape&reel - add SMT&R after part no.

l All electrical parameters 100% tested

l Custom electrical selections available

APPLICATIONS

l Line receivers

l Digital logic ground isolation

l Telephone ring detector

l Current loop receiver
