Separate pins for the photodiode and output stage enable TTL compatible saturation voltages with high speed operation. Photodarlington 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 k 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 0C to 70C.

Device considered a two-terminal device: pins 1, 2, 3 and 4 shorted together and pins 5, 6, 7, and 8 shorted together. 8. Using a resistor between pin 5 and 7 will decrease gain and delay time. 9. Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading edge of the common mode pulse, VCM, to assure that the output will remain in a logic high state (i.e. VO>2.0 V) common mode transient immunity in logic low level is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common mode pulse signal, VCM, to assure that the output will remain in a logic low state (i.e. VO<0.8 V). 10.In applications where dv/dt may exceed 50,000 V/s (such as state discharge) a series resistor, RCC should be included to protect IC from destructively high surge currents.
