General Description
• Matched Delay Times
• Low Supply Current
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.

With Logic “0” Input: 100µA
• Low Output Impedance: 4Ω
• Pinout Same as TC1410/TC1411/TC1413
Applications
• Switch Mode Power Supplies
• Pulse Transformer Drive
• Line Drivers
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.
