General Description

The TC4420/TC4429 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 and more efficient operation

versus bipolar drivers.

Both devices have TTL/CMOS compatible inputs that

can be driven as high as V

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

delay time is only 55 ns (typ.) and the output rise and fall

times are only 25 ns (typ.) into 2500 pF across the

usable power supply range.

Unlike other drivers, the TC4420/TC4429 are virtually

latch-up proof. They replace three or more discrete

components, saving PCB area, parts and improving

overall system reliability.
