6N138/6N139

Vishay Semiconductors

DESCRIPTION

High common mode transient immunity and very high current

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.

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 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.
