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.

Access to the base terminal allows adjustment to the gain

bandwidth.

The 6N139 is suited for low power logic applications

involving CMOS and low power TTL applications. A 400 %

current transfer ratio with only 0.5 mA of LED current is

guaranteed.

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.

FEATURES
