TC1412
TC1412N
2A HIGH-SPEED MOSFET DRIVERS
GENERAL DESCRIPTION
FEATURES
The TC1412/1412N are 2A CMOS buffer/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 TC1412/1412N can easily
switch 1000 pF gate capacitance in 18 ns 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 rise and fall time edges are matched to allow driving
short-duration inputs with greater accuracy.
