GENERAL DESCRIPTION
The TC4420/4429 are 6A (peak), single output MOSFET
drivers. The TC4429 is an inverting driver (pin-compatible
with the TC429), while the TC4420 is a non-inverting driver.
These drivers are fabricated in CMOS for lower power, more
efficient operation versus bipolar drivers.
Both devices have TTL-compatible inputs, which can be
driven as high as V
DD
+ 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. Propagational delay time is only 55nsec (typ.)
and the output rise and fall times are only 25nsec (typ.) into
2500pF across the usable power supply range.
Unlike other drivers, the TC4420/4429 are virtually
latch-up proof. They replace three or more discrete compo-
nents saving PCB area, parts and improving overall system
reliability.
