They 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; they 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 either damage or logic upset, more than 1A 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 TC4421/4422 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 device to be driven from slowly rising or falling waveforms. 2 3 4 5 6 7 s s APPLICATIONS s s s s s Line Drivers for Extra-Heavily-Loaded Lines Pulse Generators Driving the Largest MOSFETs and IGBTs Local Power ON/OFF Switch Motor and Solenoid Driver PIN CONFIGURATIONS 5-Pin TO-220 8-Pin Plastic DIP/CerDIP VDD 1 8 VDD 7 OUTPUT ORDERING INFORMATION Part No. TC4421CAT TC4421CPA TC4421EPA TC4421MJA TC4422CAT TC4422CPA TC4422EPA TC4422MJA Package 5-Pin TO-220 8-Pin PDIP 8-Pin PDIP 8-Pin CerDIP 5-Pin TO-220 8-Pin PDIP 8-Pin PDIP 8-Pin CerDIP Temperature Range 0°C to +70°C 0°C to +70°C – 40°C to +85°C – 55°C to+125°C 0°C to +70°C 0°C to +70°C – 40°C to +85°C – 55°C to+125°C INPUT 2 TC4421 TC4422 Tab is Common to VDD INPUT GND VDD GND OUTPUT NC 3 GND 4 TC4421 TC4422 6 OUTPUT 5 GND NOTE: Duplicate pins must both be connected for proper operation.

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: TA = 25°C with 4.5V ≤ VDD ≤ 18V unless otherwise specified.
