General Description
The TC1412/TC1412N are 2A CMOS buffers/drivers.
They do 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 electrostatic
discharge (ESD) up to 2.0 kV (HBM) and 400V (MM).
As MOSFET drivers, the TC1412/TC1412N can easily
charge a 1000 pF gate capacitance in 18 ns with
matched rise and fall times. To ensure that the
MOSFET’s intended state will not be affected even by
large transients, low enough impedance in both the ‘On’
and ‘Off’ states are provided. The leading and trailing
edge propagation delay times are also matched to allow
driving short-duration inputs with greater accuracy.
