THE DIGITAL LOGIC INVERTER

Transition region

Operation is described by voltageTransfer characteristic (VTC).

VIL –max value for for input interpreted

as logic zero

VIH –max value for for input interpreted

as logic oneNoise margins 1-1

The Ideal VTC

Ideal inverter maximizes noise marginsAnd distributes them equally between The low and high regions.(No transition region.)
