Abstract
The invention comprises a gallium arsenide driver with float capability for logic high and logic low signals including logic means for receiving an input signal and providing logic high and low signals therefrom. Level shift means responsive to the high and low signals downshift the voltage levels thereof. Common gate means responsive to the downshifted signal voltage levels amplify these signals, and output source-follower means responsive to the amplified signals provide output signals to a pad.
