Electrical and Mechanical Specifications
Table 2 provides the absolute maximum ratings, and Table 3
shows the recommended operating conditions. Electrical
specifications are provided in Tables 4 through 6.
The state of the SKY66420-11 is determined by the control logic
shown in Tables 7 and 8. Typical performance characteristics are
shown in Figures 3 through 10.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters
set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
ESD HANDLING:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.
