Description
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.
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.

3.1Supply Input (VDD)
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.
3.2Control 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.
3.3CMOS Push-pull Output (OUTPUT)
The MOSFET driver output is a low impedance, CMOS
push-pull style output, capable of driving a capacitive
load with 1A peak currents.
3.4Ground (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.

•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.”
