3A DUAL HIGH-SPEED POWER MOSFET DRIVERS
FEATURES
GENERAL DESCRIPTION
■ High Peak Output Current .................................. 3A
■ Wide Operating Range ..........................4.5V to 18V
■ High Capacitive Load
Drive Capability ......................... 1800 pF in 25nsec
■ Short Delay Times ............................. < 40nsec Typ
■ Matched Rise/Fall Times
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
farmoredemandingelectricalenvironmentsthantheirante-
cedents.
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.
■ Low Supply Current
— With Logic "1" Input ................................ 3.5 mA
— With Logic "0" Input ................................ 350 µA
■ 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....................................................4 kV
■ Pinouts Same as TC1426/27/28; TC4426/27/28

divide the stated value by 4.
*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings (See page 2) may
cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions above
those indicated in the operational sections of the specifications is not
implied. Exposure to Absolute Maximum Rating Conditions for extended
periods may affect device reliability.
