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. As MOSFET drivers, the TC4423M/TC4424M/ TC4425M can easily charge 1800 pF gate capacitance in under 35 nsec, while 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. The TC4423M/TC4424M/TC4425M inputs may be driven directly from either TTL or CMOS (2.4V to 18V). In addition, 300 mV of hysteresis is built-in to provide noise immunity and to allow the device to be driven from slowly rising or falling waveforms.
