US 2014/0176227 A1 · DATA CONTROL CIRCUIT

Abstract

A data control circuit includes an output stage circuit, a switch circuit, and an impedance module. The output stage circuit outputs a data signal. An input terminal of the switch circuit is coupled to an output terminal of the output stage circuit, and an output terminal of the switch circuit is coupled to a post-stage circuit. According to a control of a control signal, the switch circuit determines whether to transmit the data signal of the output stage circuit to the post-stage circuit. The impedance module is configured in the output stage circuit, configured between the output stage circuit and the switch circuit, or configured in the switch circuit. Here, the impedance module reduces noise flowing from the switch circuit to the output stage circuit.
