DESCRIPTION
The CLM4426 series are dual CMOS drivers are designed to
drive capacitive, resistive and inductive loads switching
1000pF gate capacitances in under 30ns while providing low
impedances in both the ON and OFF states to insure the
MOSFET's intended state will not be affected. All terminals
are fully protected up to 4kV of ESD.

Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields.
Stresses above those listed under "Absolute Maximum Ratings" may
cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other
conditions above those indicated in the operation sections of the
specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
