TC4420M/TC4429M 6A High-Speed MOSFET Drivers Features General Description Latch-Up Protected: Will Withstand >1.5A The TC4420M/TC4429M are 6A (peak), single-output Reverse Output Current MOSFET drivers. The TC4429M is an inverting driver (pin-compatible with the TC429M), while the TC4420M Logic Input: Will Withstand Negative Swing is a non-inverting driver. These drivers are fabricated in Up To 5V CMOS for lower power and more efficient operation ESD Protected: 4 kV versus bipolar drivers. Matched Rise and Fall Times: Both devices have TTL/CMOS-compatible inputs, - 25 ns (2500 pF load) + 0.3V or as low as which can be driven as high as V DD High Peak Output Current: 6A -5V without upset or damage to the device.
