TC4426AMJA

General Description

The TC4426AM/TC4427AM/TC4428AM are improved versions of the earlier TC4426M/TC4427M/TC4428M family of MOSFET drivers. In addition to matched rise and fall times, the TC4426AM/TC4427AM/TC4428AM devices have matched leading and falling edge propagation delay times.
These devices are highly latch-up resistant under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin.
They can accept, without damage or logic upset, up to 500 mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against Electrostatic Discharge (ESD) up to 4 kV.
The TC4426AM/TC4427AM/TC4428AM MOSFET drivers can easily charge/discharge 1000 pF gate capacitances in under 30 ns, while providing low enough impedances in both the on and off states to ensure the MOSFETs intended state will not be affected, even by large transients.
