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.
