**The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous

voltage rating. For the continuous voltage rating refer to the VDE 0884 Insulation Characteristics Table (if applicable), your equipment level

safety specification or Agilent Application Note 1074 entitled "Optocoupler Input-Output Endurance Voltage."

Notes:

1. Pin 5 should be the most negative voltage at the detector side.

2. Each channel.

3. DC CURRENT TRANSFER RATIO (CTR) is defined as the ratio of output collector current, IO, to the forward LED input current, IF, times 100%.

4. Device considered a two-terminal device: pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7, and 8 shorted together.

5. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.

6. Common mode transient immunity in a Logic High level is the maximum tolerable (positive) dVCM/dt 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 a Logic Low level is the

maximum tolerable (negative) dVCM/dt of the common mode pulse, VCM, to assure that the output will remain in a Logic Low state

(i.e., VO < 0.8 V).

7. In applications where dV/dt may exceed 50,000 V/

µs (such as static discharge) a series resistor, RCC, should be included to protect the

detector IC from destructively high surge currents. The recommended value is RCC = 110 Ω.

8. Use of a 0.1

µF bypass capacitor connected between pins 5 and 8 adjacent to the device is recommended.

9. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 3000 V rms for 1 second (leakage

detection current limit, II-O < 5 µA).

10. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 V rms for 1 second (leakage

detection current limit, II-O < 5 µA).

11. Measured between the LED anode and cathode shorted together and pins 5 through 8 shorted together.

12. Derate linearly above 65˚C free-air temperature at a rate of 2.3 mW/˚C for the SO-8 package.
