General Description
The TC1412/TC1412N are 2A CMOS buffers/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,
withou t dama ge or l ogic u ps et, up to 500 mA of c urrent
of eit her p ola rity bei ng forc ed b ack in to th eir o utp ut. Al l
terminals are fully protected against up to 4 kV of
electrostatic discharge.
As MOSFET drivers, the TC1412/TC1412N can easily
charge a 1000 pF gate capacitance in 18 nsec 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 leading and
trailing edge prop agatio n delay times are also matc hed
to allow driving short-duration inputs with greater
accuracy.

3.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1: PIN FUNCTION TABLE
3.1 Supply Input (VDD)
The VDD in put is the bia s supply for the M OSFET driver
and is rated for 4.5V to 16V with respect to the ground
pin. The VDD input should be bypassed to ground with
a local ceramic capacitor. The value of the capacitor
shoul d be chos en base d on the capaciti ve load that is
being driven. A value of 1.0 µF is suggested.
3.2 Control Input (INPUT)
The MOSFET driver input is a high-impedance,
TTL/CM OS-c o mpatible 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
(OUTPUT)
The MOS FET driver ou tput is a low-im pedance, C MOS
push-pull style output, capable of driving a capacitive
load with 2A peak currents.
3.4 Ground (GND)
The ground pin s are the return pa th for the bias current
and for the high peak currents that discharge the load
capa citor. The ground pi ns shoul d be tied i nto a groun d
plane or have very short traces to the bias supply
source retur n.

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that i ts family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• The re are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is c onstantly evolving. We a t Microc hip are co m mitted to continuously improving the code prot ect ion featur es of our
products. Attempts to break Microchip’ s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
