Abstract
An output driver to reduce totem pole current is provided. The output driver comprises a first delay element outputting a delayed first driver signal, and a first selection unit receiving as an input the first driver signal and the delayed first driver signal. The output driver further comprises a second delay element outputting a delayed second driver signal and a second selection unit receiving as an input the second driver signal and the delayed second driver signal. A selection signal for the first selector is the first driver signal, and the selection signal for the second selector is an inverted first driver signal, such that a path that is not presently driving is switched off first, prior to the opposing driver being turned on.
