Power Dissipation
Low Power Systems-Ground Isolation
Photo darlington operation is achieved by tying the
V
CC
and V
O
terminals together. Access to the base
terminal allows adjustment to the gain bandwidth.
The 6N138 is ideal for TTL applications since the
300 % minimum current transfer ratio with an LED
current of 1.6 mA enables operation with one unit
load-in and one unit load-out with a 2.2 kΩ pull-up
resistor.
The 6N139 is best suited for low power logic applica-
tions involving CMOS and low power TTL. A 400 %
current transfer ratio with only 0.5 mA of LED current
is guaranteed from 0 °C to 70 °C
Caution: Due to the small geometries of this device, it should be
handled with Electrostatic Discharge (ESD) precautions. Proper
grounding would prevent damage further and/or degradation which
may be induced by ESD.

Description
High common mode transient immunity and very high
current ratio together with 5300 V
RMS
insulation are
achieved by coupling and LED with an integrated high
gain photo detector in an eight pin dual-in-line pack-
age. Separate pins for the photo diode and output
stage enable TTL compatible saturation voltages with
high speed operation.
