General Description:

The

versions of the earlier TC4426/TC4427/TC4428 family

of MOSFET drivers. In addition to matched rise and fall

times, the TC4426A/TC4427A/TC4428A 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 TC4426A/TC4427A/TC4428A MOSFET drivers

can

capacitances in under 30 ns. These devices provide

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.
