TC1411/TC1411N  
1A High-Speed MOSFET Drivers  
Features  
Description  
• Latch-Up Protected: Will Withstand 500 mA  
Reverse Current  
The TC1411/TC1411N are 1A CMOS buffers/drivers.  
They will not latch-up under any conditions within their  
power and voltage ratings. They are not subject to  
damage when up to 5V of noise spiking of either  
polarity occurs on the ground pin. They can accept,  
without damage or logic upset, up to 500 mA of current  
of either polarity being forced back into their output. All  
terminals are fully protected against up to 4 kV of  
electrostatic discharge.  
• Input Will Withstand Negative Inputs Up to 5V  
• ESD Protected: 4 kV  
• High Peak Output Current: 1A  
• Wide Input Supply Voltage Operating Range:  
- 4.5V to 16V  
• High Capacitive Load Drive Capability:  
- 1000 pF in 25 nsec  
As MOSFET drivers, the TC1411/TC1411N can easily  
charge a 1000 pF gate capacitance in 25 nsec with  
matched rise and fall times, and provide low enough  
impedance in both the ON and the OFF states to  
ensure the MOSFET’s intended state will not be  
affected, even by large transients. The leading and  
trailing edge propagation delay times are also matched  
to allow driving short-duration inputs with greater  
accuracy.  
• Short Delay Time: 30 nsec Typ.  
• Matched Delay Times  
• Low Supply Current

3.3  
CMOS Push-pull Output (OUTPUT)  
The VDD input is the bias supply for the MOSFET driver  
and is rated for 4.5V to 16V with respect to the ground  
pin. The VDD input should be bypassed to ground with  
a local ceramic capacitor. The value of the capacitor  
should be chosen based on the capacitive load that is  
being driven. A value of 1.0 µF is suggested.  
The MOSFET driver output is a low impedance, CMOS  
push-pull style output, capable of driving a capacitive  
load with 1A peak currents.  
3.4  
Ground (GND)  
The ground pins are the return path for the bias current  
and for the high peak currents which discharge the load  
capacitor. The ground pins should be tied into a ground  
plane or have very short traces to the bias supply  
source return.  
3.2  
Control Input (INPUT)  
The MOSFET driver input is a high-impedance,  
TTL/CMOS-compatible input. The input has 300 mV of  
hysteresis between the high and low thresholds that  
prevents output glitching even when the rise and fall  
time of the input signal is very slow.

Note the following details of the code protection feature on Microchip devices:  
Microchip products meet the specification contained in their particular Microchip Data Sheet.  
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the  
intended manner and under normal conditions.  
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our  
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data  
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.  
Microchip is willing to work with the customer who is concerned about the integrity of their code.  
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not  
mean that we are guaranteeing the product as “unbreakable.”  
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our  
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts  
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is provided only for your convenience
