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.

PIN DESCRIPTIONS
The descriptions of the pins are listed in
Table 3-1
.
3.1
Supply Input (V
DD
)
The V
DD
input is the bias supply for the MOSFET driver
and is rated for 4.5V to 16V with respect to the ground
pin. The V
DD
input should be bypassed to ground with
a local ceramic capacitor. The value of the capacitor is
chosen based on the capacitive load that is being
driven. A value of 1.0 µF is suggested.
3.2
Control Input (IN)
The MOSFET driver input is a high-impedance,
TTL/CMOS-compatible input. The input has 300 mV of
hysteresis between the high and low thresholds which
prevents output glitching even when the rise and fall
time of the input signal is very slow.
3.3
CMOS Push-Pull Output
(OUT, OUT)
The MOSFET driver output is a low-impedance, CMOS
push-pull style output, capable of driving a capacitive
load with 2A peak currents.
3.4
Ground (GND)
The ground pins are the return path for the bias current
and for the high peak currents that discharge the load
capacitor. The ground pins should be tied into a ground
plane or have very short traces to the bias supply
source return.
3.5
No Connect (NC)
No internal connection.
