This is a high current buffer/driver that can drive large MOSFETs and IGBTs. It has good anti-interference ability and can work at 3V to 18V voltage.
The TelCom TC4421 and TC4422 are high current buffer/drivers designed to drive large MOSFETs and IGBTs. These devices feature tough CMOS construction with a high peak output current of 9A and are immune to latch-up under normal operating conditions. They accept inputs directly from TTL or CMOS logic levels (3V to 18V) and include built-in hysteresis for noise immunity.

They are used for line drivers for heavily loaded lines, pulse generators, driving large MOSFETs and IGBTs, local power ON/OFF switches, and motor or solenoid drivers.
Yes, the inputs may be driven directly from either TTL or CMOS logic levels ranging from 3V to 18V.
Yes, they are essentially immune to any form of upset except direct overvoltage or over-dissipation and cannot be latched under any conditions within their power and voltage ratings.
