General Description

The MIC4423/4424/4425 family are highly reliable BiCMOS DMOS buffer/driver/MOSFET drivers. They are higher out put current versions of the MIC4426/4427/4428, which are improved versions of the MIC426/427/428. All three familie are pin-compatible. The MIC4423/4424/4425 drivers are capable of giving reliable service in more demanding electrical environments  than  their  predecessors.
