General Description

The TC4423M/TC4424M/TC4425M devices are a family of 3A, dual output buffers/MOSFET drivers. Pin-compatible with both the TC4426M/TC4427M/ TC4428M and TC4426AM/4427AM/4428AM families (dual 1.5A drivers), the TC4423M/TC4424M/TC4425M family has an increased latch-up current rating of 1.5A, making them even more robust for operation in harsh electrical environments.
