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 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.)

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 components

saving PCB area, parts and improving overall system

reliability.
