Patent ID: 8766677

Claim:
A signal input circuit, comprising: a control signal input terminal configured for receiving a control signal; at least one common signal input terminal each configured for receiving a corresponding common signal; at least one first signal output terminal each configured for outputting a corresponding first signal; at least one first signal unit, wherein an input terminal of each of said at least one first signal unit is coupled to said at least one common signal input terminal, wherein an output terminal of each of said first signal unit is coupled to said at least one first signal output terminal, and wherein said first signal unit includes a latch unit configured for receiving said corresponding common signal and outputting said corresponding common signal as said corresponding first signal under control of said control signal; at least one second signal output terminal each configured for outputting a corresponding second signal; and at least one second signal unit each configured for receiving said corresponding common signal and outputting said corresponding common signal as said corresponding second signal under control of said control signal, wherein an input terminal of said at least one second signal unit is coupled to said at least one common signal input terminal, wherein an output terminal of each of said at least one second signal unit is coupled to said at least one second signal terminal, and wherein each second signal unit is configured for receiving a corresponding common signal and outputting the corresponding common signal as a second signal based on the control signal, wherein said second signal unit comprises a plurality of flip-flops coupled in series, wherein an input terminal of a first flip-flop of the plurality of flip-flops is used as an input terminal of said second signal unit, and wherein each input terminal of other flip-flops of the plurality of flip-flops is coupled to an output terminal of a left adjacent flip-flop, and wherein an output terminal of a right-most flip-flop is used as an output terminal of said second signal unit.
