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.

CHARACTERISTICS
†
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. These
are stress ratings only and functional operation of the device
at these or any other conditions above those indicated in the
operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.
