6N138 Optocoupler; THT; Ch: 1; OUT: Darlington ; Uisol: 5,3kV
Description
6N138 OPTOCOUPLER
High Speed Optocoupler, 100 kBd,
Low Input Current, Photodiode Darlington Output
DESCRIPTION
High common mode transient immunity and very high current
ratio together with 5300 VRMS 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 VCC and
VO 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.
