The TC429 is a high-speed, single output, CMOS-leveltranslator and driver. Designed specifically to drivehighly capaciTIve power MOSFET gates, the TC429features a 2.5Ω output impedance and 6A peak outputcurrent drive.A 2500 pF capaciTIve load will be driven to 18V in25 nsec. The rapid switching TImes with largecapaciTIve loads minimize MOSFET switching powerlosses.A TTL/CMOS input logic level is translated into anoutput voltage swing that equals the supply voltage andwill swing to within 25 mV of ground or VDD. Input voltageswing may equal the supply voltage. Logic inputcurrent is under 10 μA, making direct interface toCMOS/bipolar switch-mode power supply controllerseasy. Input “speed-up” capacitors are not required.The CMOS design minimizes quiescent power supplycurrent. With a logic ‘1’ input, power supply current is5 mA maximum and decreases to 0.5 mA for logic ‘0’inputs.For dual output MOSFET drivers, see the TC426/TC427/TC428 (DS21415), TC4426/TC4427/TC4428(DS21422) and TC4426A/TC4427A/TC4428A(DS21423) data sheets.For non-inverting applications, or applications requiringlatch-up protection, see the TC4420/TC4429(DS21419) data sheet.
