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 500 mA of current of either polarity being forced back into their output. All terminals are fully protected against up to 4 kV of electrostatic discharge. As MOSFET drivers, the TC1412/1412N can easily switch 1000 pF gate capacitance in 18 ns 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. 2 3 4 5 6 7 s s ORDERING INFORMATION PIN CONFIGURATIONS VDD 1 IN 2 NC 3 GND 4 2 6, 7 8 VDD 7 OUT VDD 1 IN 2 NC 3 GND 4 2 6, 7 8 VDD 7 OUT Part No. TC1412COA TC1412CPA TC1412EOA TC1412EPA TC1412NCOA TC1412NCPA TC1412NEOA TC1412NEPA Package 8-Pin SOIC 8-Pin Plastic DIP 8-Pin SOIC 8-Pin Plastic DIP 8-Pin SOIC 8-Pin Plastic DIP 8-Pin SOIC 8-Pin Plastic DIP Temp.

Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS: Over operating temperature range with 4.5V ≤ VDD ≤ 16V, unless otherwise specified. Typical values are measured at TA = 25°C; VDD = 16V.
