Abstract
An improved flip-flop with a scan path comprises a front page circuit driven in response to a clock signal and multiplexers for receiving a data signal and a scan test signal. Each of the multiplexers comprises a single stage of FETs connected in series between a power source and a ground. This arrangement can remarkably improve an operation frequency.
