Abstract
A MOS driver circuit has a first output transistor and a second output transistor which are driven in push-pull into a conducting state by a first driver stage having first high impedance and first low impedance elements and a second driver stage having second high impedance and second low impedance elements, respectively. The high impedance driver elements drive the output transistors into a conducting or nonconducting state and the low impedance driver elements hold the output transistors in the nonconducting state. The junction of the output transistors can be connected to a load. A holding stage for each driver stage is cross coupled to a high impedance driver element of one output transistor and the low impedance driver element of the other output transistor, so as to drive one output transistor in the conducting state while holding the other output transistor in a nonconducting state. As a result, shunt currents between the output transistors are avoided even in the presence of output noise.
