or VDD Space-Saving 8-Pin SOIC and 8-Pin 6x5 DFN
Packages The TC4420/TC4429 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 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 better drive voltage margin, especially during
power-up/power-down sequencing. Propagational
delay time is only 55 ns (typ.) and the output rise and fall …
