GENERAL DESCRIPTION

The TC429 is a high-speed, single CMOS-level translator and driver. Designed specifically to drive highly capacitive power MOSFET gates, the TC429 features 2.5? output impedance and 6A peak output current drive.

A 2500pF capacitive load will be driven 18V in 25nsec. Delay time through the device is 60nsec. The rapid switching times with large capacitive loads minimize MOSFET transition 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 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.
