System Design Practice (TC4426/7/8, TC4426A/7A/8A)
The TC4426/4427/4428 are high-speed power MOSFET drivers built using Microchip Technology's tough CMOS process. They are improved versions of the earlier TC426/427/428 family of high-speed power MOSFET drivers (with which they are pin compatible) and are capable of giving reliable service in far more demanding electrical environments. They will not latch up 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 500mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against up to 4kV of electrostatic discharge.
