This document introduces TC4420/TC4429 6A (peak) single-output MOSFET drivers. 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 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 55 ns (typ.) and the output impedance is 2.5 Ω.
