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 package. Separate pins for the
photo diode and output stage enable TTL compatible
saturation voltages with high speed operation.
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 applications
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.
