Title: Latch circuit
Inventor: NEMOTO MASAHISA
IPC: H03K3/356
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To reduce the disturbance in an output waveform. SOLUTION: The latch circuit receives a logic level of input data from an inverter 11 via a data input terminal D in a conductive state of a FET 12 and uses inverters 13, 14 connected in parallel with opposite connection polarity to latch the received level. For example, suppose that the data input terminal D is set to a low level, a node N2 of an input section of the inverter 13 is set to a high level and a high level clock signal CK is given to a Schottky gate of the FET 12 via inverters 15, 16, then an inverter 17 sets a FET 18 to be conductive and a FET 20 sets a FET 19 to be conductive. Since the two FETs 18, 19 form a discharge path between the node N2 and ground, the conductive FETs 18, 19 assist the node N2 to discharge its charges thereby allowing the level of the node N2 to be changed quickly.
