White Electronic Designs Corp. reserves the right to change products or specications without notice.
*Stress greater than those listed under "Absolute Maximum Ratings" may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions greater than those indicated
in the operational sections of this specication is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
