Title: Latch circuit
Inventor: NARITA KANEYUKI
IPC: H03K3/037
Filed: 1988-02-10
Abstract: PURPOSE:To avoid malfunction of the circuit even if a spike noise is given to a strobe signal by feeding back an output of a latch circuit or a D flip-flop to a data input of the latch circuit or D flip-flop via a multiplexer circuit. CONSTITUTION:When a spike noise with a short pulse width is given to a strobe terminal signal 6 at a time t2, the multiplexer circuit 4 selects a level '1' of a data input terminal signal 7 and the level of the multiplexer output terminal signal 9 goes from '0' to '1' after the elapse of a transmission delay time between the strobe terminal 2 and the multiplexer output terminal Y. Moreover, the time of level '1' corresponds to the pulse width of spike noise. When a spike noise is given to a strobe terminal ST of the latch circuit 5, since the output terminal signal 9 of the multiplexer circuit 4 is still logical '0', '0' is outputted to a data output terminal 3. Thus, even if the pulse width of the spike noise is shorter than the transmission delay time between the strobe terminal 2 and the output terminal Y of the multiplexer circuit 4, the circuit does not cause any malfunction.
