TC4420/TC4429 are 6A (peak), single output MOSFET drivers.

The TC4420 6A High-Speed MOSFET Drivers 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 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 a better drive voltage margin, especially during power-up/power-down sequencing. The propagational 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.

Notes:

1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual colour of the item because of different photographing light, angle and display monitor.
