In addition, all terminals are fully protected against up to 4kV of electrostatic discharge. The TC4421/TC4422 inputs may be driven directly from either TTL or CMOS (3V to 18V). In addition, 300mV of hysteresis is built into the input, providing noise immunity and allowing the device to be driven from slowly rising or falling waveforms.
