Description

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 fabricated in CMOS for lower power, more efficient operation versus bipolar drivers. Both devices have TTL-compatible inputs, which can be driven as high as VDD + 0.3V or as low as 5V without upset or damage to the device. This of TC4429 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 55nsec (typ.) and the output rise and fall times are only 25nsec (typ.) into 2500pF across the usable power supply range. Unlike other drivers, the TC4429 are virtually latch-up proof. They replace three or more discrete components saving PCB area, parts and improving overall system reliability.
