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 VDD. 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.

For dual devices, see the TC426/TC427/TC428

data sheet.

For noninverting applications, or applications requiring

latch-up protection, see the TC4420/TC4429 data sheet.
