ABSTRACT:
An integrated circuit (20) includes multiple output buffers (30, 50, 70) which switch substantially simultaneously. The output buffers (30, 50, 70) are connected together via a common node (25). Before any one of the output buffers (30, 50, 70) actively drives its corresponding output node to an appropriate logic state, a coupling circuit (42) in the output buffer (30) evaluates whether the new logic state matches the old logic state. If the coupling circuit (42) determines that the logic states are different, then it couples the output node to the common node (25). With each output buffer in the group of multiple output buffers (30, 50, 70) functioning similarly, energy is conserved by using the charge stored in the low-going nodes to charge up the high-going nodes.
