The TC4420M/TC4429M are 6A (peak), single-outputMOSFET drivers. The TC4429M is an inverting driver(pin-compatible with the TC429M), while the TC4420Mis a non-inverting driver. These drivers are fabricated inCMOS for lower power and more efficient operationversus bipolar drivers.Both devices have TTL/CMOS-compatible inputs,which can be driven as high as VDD + 0.3V or as low as-5V without upset or damage to the device. Thiseliminates the need for external level-shifting circuitryand its associated cost and size. The output swing israil-to-rail, ensuring better drive voltage margin,especially during power-up/power-down sequencing.The propagational delay time is only 55 ns (typ.), whilethe output rise and fall times are only 25 ns (typ.) into2500 pF across the usable power supply range.Unlike other drivers, the TC4420M/TC4429M arevirtually latch-up proof. They replace three or morediscrete components, saving PCB area and parts whileimproving overall system reliability.
