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 VDD + 0.3V or as low as
-5V without upset or damage to the device. This
eliminates 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 propagational delay time is only 55 ns (typ.), while
the output rise and fall times are only 25 ns (typ.) into
2500 pF across the usable power supply range.
Unlike other drivers, the TC4420M/TC4429M are
virtually latch-up proof. They replace three or more
discrete components, saving PCB area and parts while
improving overall system reliability.
