Abstract
The present invention discloses a multi-function circuit module having voltage level shifting function and data latching function via switching a plurality of switch elements. The multi-function circuit module includes a first circuit module, a fourth switch element, and a fifth switch module, wherein the first circuit module further includes a first switch module, a second switch module, and a third switch module. The multi-function circuit module can substantially reduce the circuit layout area. For example, when the multi-function circuit module of the present invention is applied in a source driving chip circuit, the multi-function circuit module can replace the original low-to-high voltage level shifting circuit and data latching circuit, so as to attain the purpose of reducing the chip area.
