NOTES:- 1. Derate linearly above 70oC free air temperature at a rate of 0.8 mA/C. 2. Derate linearly above 70oC free air temperature at a rate of 1.6 mA/C. 3. Derate linearly above 70oC free air temperature at a rate of 0.9 mW/C. 4. Derate linearly above 70oC free air temperature at a rate of 1.0 mW/C. 5. Each channel . 6. CURRENT TRANSFER RATIO is defined as the ratio of output collector current,IO , to the forward LED input current, IF times 100%. 7. Device considered a two-terminal device: pins 1,2,3,and 4 shorted together and pins 5,6,7,and 8 shorted together. 8. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together. 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 > 2.0V). 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 Logic Low state (i.e. VO< 0.8V).

Applications
Analog circuit power terminals. A combination of high frequency decoupling capacitors on each side are suggested, such as paralleled 0.1 µF and 0.001 µF. These supply terminals are separated from PLLVDD and DVDD internal to the device to provide noise isolation. They should be tied at a low impedance point on the circuit board.
Features
The WT411A is a fixed frequency improved performance pulse width modulation control circuit with complete house- keeping circuitry for use in the secondary side of SMPS (Switched Mode Power Supply). It contains various func- tions, which are overvoltage protection, undervoltage protec- tion, over current protection, remote on/off control, power good signal generator, etc.
