3A DUAL HIGH-SPEED POWER MOSFET DRIVERS
GENERAL DESCRIPTION
FEATURES
The TC4423/4424/4425 are higher output current ver-
sionsofthenewTC4426/4427/4428buffer/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
farmoredemandingelectricalenvironmentsthantheirante-
cedents.
■ High Peak Output Current .................................. 3A
■ Wide Operating Range .......................... 4.5V to 18V
■ High Capacitive Load
Drive Capability .......................... 1800pF in 25nsec
■ Short Delay Times ............................. <40nsec Typ.
■ Matched Rise/Fall Times
■ Low Supply Current
AlthoughprimarilyintendedfordrivingpowerMOSFETs,
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
loadedclocklines, coaxialcables, orpiezoelectrictransduc-
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.
— With Logic "1" Input ................................. 3.5mA
— With Logic "0" Input ................................. 350µA
■ Low Output Impedance ............................ 3.5Ω Typ.
■ Latch-Up Protected ..Will Withstand 1.5A Reverse
Current
■ Logic Input Will Withstand Negative Swing Up
to 5V
■ ESD Protected.....................................................4kV
■ Pinouts Same as TC1426/27/28; TC4426/27/28
