DESCRIPTION
High common mode transient immunity and very
high current ratio together with 2500 VAC insulation
are achieved by coupling an LED with an integrated
high gain photo detector in an eight pin dual-in-line
package. Separate pins for the photodiode and out-
put stage enable TTL compatible saturation volt-
ages with high speed operation. Photodarlington
operation is achieved by tying the VCC and VO ter-
minals 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 K
Ω pull-up
resistor.
The 6N139 is best suited for low power logic appli-
cations 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) precau-
tions. Proper grounding would prevent damage further
and/or degradation which may be induced by ESD.
