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.

Package Thermal Resistance PDIP R Operating T emperature Range oC to +70oC Power Dissipation 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.
