NOTE: Duplicate pins must both be connected for proper operation.
The TC429 is a high-speed, single CMOS-level transla-
tor and driver. Designed specifically to drive highly capaci-
tive power MOSFET gates, the TC429 features 2.5Ω output
impedance and 6A peak output current drive.
A 2500pF capacitive load will be driven 18V in 25nsec.
3 ^{Delay time through the device is 60nsec. The rapid switching}
times with large capacitive loads minimize MOSFET transi-
tion power loss.
A TTL/CMOS input logic level is translated into an
output voltage swing that equals the supply and will swing
to within 25mV of ground or V_DD. Input voltage swing may
equal the supply. Logic input current is under 10µA, making
direct interface to CMOS/bipolar switch-mode power supply
4 ^{controllers easy. Input "speed-up" capacitors are not}
required.
The CMOS design minimizes quiescent power supply
current. With a logic 1 input, power supply current is 5mA
maximum and decreases to 0.5mA for logic 0 inputs.

data sheet.
For noninverting applications, or applications requiring
latch-up protection, see the TC4420/TC4429 data sheet.
