TC4420-6A High Speed MOSFET Driver
Overview 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 engineered for low power consumption and operate more efficiently in CMOS with bipolar drivers. Both devices feature TTL compatible inputs that can drive VDD+ as high as 0.3V or as low as -5V without worrying or damaging the device. This eliminates the need for external level shifting circuitry and its associated expense, size. The output swings rail-to-rail, ensuring better advance voltage headroom, especially during power-up/power-down sequencing. Breeding delay time is only 55nsec (typ) and output rise and fall times are only 25nsec (typ) to 2500pF over the entire usable supply voltage range. Unlike other drivers, the TC4420/4429 is almost latch proof. They replace three or more discrete components to save PCB area and improve overall system components and reliability.
