General Description

The TC1412/TC1412N 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 500mA of current

of either polarity being forced back into their output. All

terminals are fully protected against up to 4kV of

electrostatic discharge.

As MOSFET drivers, the TC1412/TC1412N can easily

charge a 1000pF gate capacitance in 18nsec 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.
