General Description
The TC429 is a high-speed, single output, CMOS-level
translator and driver. Designed specifically to drive
highly capacitive power MOSFET gates, the TC429
features a 2.5output impedance and 6A peak output
current drive.
A 2500 pF capacitive load will be driven to 18V in
25 nsec. The rapid switching times with large
capacitive loads minimize MOSFET switching power
losses.
A TTL/CMOS input logic level is translated into an
output voltage swing that equals the supply voltage and
will swing to within 25 mV of ground or VDD. Input volt-
age swing may equal the supply voltage. Logic input
current is under 10 µA, 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
5 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 requiring
latch-up protection, see the TC4420/TC4429
(DS21419) data sheet.

2.0 TYPICAL PERFORMANCE CURVES
Note:
The graphs and tables provided following this note are a statistical summary based on a limited number of
samples and are provided for informational purposes only. The performance characteristics listed herein
are not tested or guaranteed. In some graphs or tables, the data presented may be outside the specified
operating range (e.g., outside specified power supply range) and therefore outside the warranted range.
Note: Unless otherwise indicated, TA = +25°C with 7V VDD 18V.

Alphanumeric traceability code
Note: In the event the full Microchip part number cannot be marked on one line, it will
be carried over to the next line thus limiting the number of available characters
for customer specific information.
* Standard marking consists of Microchip part number, year code, week code, traceability code (facility
code, mask rev#, and assembly code). For marking beyond this, certain price adders apply. Please
