These devices are high-current buffer/drivers capable of driving large MOSFETs and Insulated Gate Bipolar Transistors (IGBTs).
The TC4451/TC4452 have matched output rise and fall times, as well as matched leading and falling-edge propagation delay times.
The TC4451/TC4452 devices also have very low crossconduction current, reducing the overall power dissipation of the device.
These devices are essentially immune to any form of upset, except direct overvoltage or over-dissipation.
They cannot be latched under any conditions within their power and voltage ratings.
These parts are not subject to damage or improper operation when up to 5V of ground bounce is present on their ground terminals.
They can accept, without damage or logic upset, more than 1.
5A inductive current of either polarity being forced back into their outputs.
In addition, all terminals are fully protected against up to 4 kV of electrostatic discharge.
The TC4451/TC4452 inputs may be driven directly from either TTL or CMOS (3V to 18V).
In addition, 300 mV of hysteresis is built into the input, providing noise immunity and allowing the ...
