Abstract

A zero static power programmable logic cell that operates without I.sub.cc leakage in the circuit being driven when the control nodes are set to V.sub.cc or ground, and has a decreased switching skew is provided. The logic cell utilizes stacked transistors and separates the output node from the input nodes by forming an inverter stage based on the current state of operation. The inverter stage isolates the output node from the input nodes, while also providing gain to the next stage. This configuration provides for a more compact cell design and prevents I.sub.cc leakage in the circuitry being driven by the logic cell.
