描述 Description

The TC4423/4424/4425 are higher output current versions of the new TC4426/4427/4428 buffer/gate drivers which, in turn, are improved versions of the earlier TC426/427/428 series. All three families are pin-compatible. The TC4423/4424/4425 gate 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 gate 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, or piezoelectric transducers can all be driven from the TC4423/4424/4425. The only known limitation on loading is the total power dissipated in the driver must be kept within the maximum power dissipation limits of the package.
