The TC4426/4427/4428 are improved versions of the earlier TC426/427/428 family of buffer/gate drivers (with which they are pin compatible). They will not latch up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5 V 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 up to 2 kV of electrostatic discharge. As MOSFET gate drivers, the TC4426/4427/4428 can switch 1,000 pF gate capacitances in 25 ns, and provide low enough impedances in both the ON and OFF states to ensure the MOSFETs intended state will not be affected by large transients. However, the recommended pin-compatible drivers are the TC4426A/27A/28A. These gate drivers have matched input to output leading edge and falling edge delays, t_D1 and t_D2, for processing short duration pulses in the 25 ns range. They are pin compatible with the TC4426/27/28.
