All three families are pin-compatible. The TC4423/ 4424/4425 drivers are capable of giving reliable service in far more demanding electrical environments than their antecedents. Although primarily intended for driving power MOSFETs, the TC4423/4424/4425 drivers are equally well-suited to driving any other load (capacitive, resistive, or inductive) which requires a low impedance driver capable of high peak currents and fast switching times. For example, heavily loaded clock lines, coaxial cables,...
