      Gate Drivers
      TC4429CAT
      The TC4420/4429 are 6A (peak),single output MOSFET drivers. The TC4429CAT 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 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 TC4420/4429 are virtually latch-up proof. They replace three or more discrete components saving PCB area, parts and improving overall system reliability.For product comparison, please consider:MCP1406Feature Latch-Up Protected: Will Withstand >1.5AReverse Output CurrentLogic Input Will Withstand Negative Swing Up to 5VMatched Rise and Fall Times: 25nsecWide Operating Range: 4.5V to 18VHigh Capacitive Load Drive: 10,000pFShort Delay Time: 55nsec Typ.Logic High Input,Any Voltage: 2.4V to VDD Low Supply Current With Logic '1' Input: 450 µA Low Output Impedance: 2.5ΩOutput Voltage Swing to Within 25mV of Ground or VDD
