General Description

The TC4420M/TC4429M are 6A (peak), single-output

MOSFET drivers. The TC4429M is an inverting driver

(pin-compatible with the TC429M), while the TC4420M

is a non-inverting driver. These drivers are fabricated in

CMOS for lower power and more efficient operation

versus bipolar drivers.

Both devices have TTL/CMOS-compatible inputs,

which can be driven as high as V

+ 0.3V or as low as

-5V without upset or damage to the device. This elimi-

nates the need for external level-shifting circuitry and

its associated cost and size. The output swing is rail-to-

rail, ensuring better drive voltage margin, especially

during power-up/power-down sequencing. The propa-

gational delay time is only 55 ns (typical), while the out-

put rise and fall times are only 25 ns (typical) into

2500 pF across the usable power supply range.

Unlike other drivers, the TC4420M/TC4429M are virtu-

ally latch-up proof. They replace three or more discrete

components, saving PCB area and parts while

improving overall system reliability.
