General Description TC4424CPA

The TC4423/TC4424/TC4425 devices are a family of

3A, dual-output buffers/MOSFET drivers. Pin compatible

with the TC1426/27/28, TC4426/27/28 and

TC4426A/27A/28A dual 1.5A driver families, the

TC4423/24/25 family has an increased latch-up current

rating of 1.5A, making them even more robust for

operation in harsh electrical environments.

As MOSFET drivers, the TC4423/TC4424/TC4425 can  easily charge 1800 pF gate capacitance in under  35 nsec, providing low enough impedances in both the  on and off states to ensure the MOSFET's intended  state will not be affected, even by large transients.
