GENERAL DESCRIPTION
The TC4423/4424/4425 are higher output current ver-
sions of the new TC4426/4427/4428 buffer/drivers, which,
in turn, are improved versions of the earlier TC426/427/428
series. 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 ante-
cedents.
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, or piezoelectric transduc-
ers 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 dissipa-
tion limits of the package.
