6N139
DESCRIPTION
High mon mode transient immunity and very high current ratio 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 patible 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 m A of LED current is guaranteed.
