OUTPUT
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
3 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.)
4 ^{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.
