The TC4426A/TC4427A/TC4428A are improvedversions of the earlier TC4426/TC4427/TC4428 familyof MOSFET drivers. In addition to matched rise and falltimes, the TC4426A/TC4427A/TC4428A devices havematched leading and falling edge propagation delaytimes.

These devices are highly latch-up resistant under anyconditions within their power and voltage ratings. Theyare not subject to damage when up to 5V of noisespiking (of either polarity) occurs on the ground pin.

They can accept, without damage or logic upset, up to500 mA of reverse current (of either polarity) beingforced back into their outputs. All terminals are fullyprotected against Electrostatic Discharge (ESD) up to4 kV.

The TC4426A/TC4427A/TC4428A MOSFET driverscan easily charge/discharge 1000 pF gatecapacitances in under 30 ns. These devices providelow enough impedances in both the on and off states toensure the MOSFET’s intended state will not beaffected, even by large transients.
