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 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. 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.
