Fairchild Semiconductor 

Recommended Operating Conditions

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended

operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not

recommend exceeding them or designing to absolute maximum ratings.

Note:

6. During power up or down, it is important to ensure that VIN+ remains LOW until both the input and output supply

voltages reach the proper recommended operating voltage to avoid any momentary instability at the output state.

Refer to “Time to Good Power” section on page 25.

Notes:

7. Device is considered a two terminal device: pins 1 to 8 are shorted together and pins 9 to 16 are shorted together.

8. 4,243 VRMS for 1-minute duration is equivalent to 5,091 VRMS for 1-second duration.

9. The Input-Output Isolation Voltage is a dielectric voltage rating as per UL1577. It should not be regarded as an

input-output continuous voltage rating. For the continuous working voltage rating, refer to the equipment level safety

specification or DIN EN/IEC 60747-5-5 Safety and Insulation Ratings Table on page 4.

Electrical Characteristics

Apply over all recommended conditions; typical value is measured at VDD1 = 5 V, VDD2 – VSS = 30 V, VE – VSS = 0 V,

TA = 25 °C unless otherwise specified.
