Abstract
PURPOSE:To avoid hazard at an output termial, by providing another input terminal to a gate casuing hazard for the output and supplying a preset signal, when a clock pulse is applied to a D type edge trigger FF circuit. CONSTITUTION:Another terminal is provided at an NAND gate 3 of an FF circuit and this is connected to a preset terminal 7. When a terminal 7 and a clear terminal 8 are respectively ''high'' and clock terminal 9 and data terminal 10 are respectively ''low'', a terminal 11 is ''low'', terminals 12-14 are ''high'', output terminal 15 is ''low'' and output terminal 16 is ''high''. When the terminal 7 changes from ''high'' to ''low'', the terminal 11 changes from ''low'' to ''high'', and the terminal changes from ''low'' to ''high'' and the terminal 16 changes from ''high'' to ''low''. When a clock pulse is applied to the terminal 9, since a signal of ''low'' is supplied from the terminal 7 to the gate 3 terminal of the terminal 13, no change is made from the delay time of gate one stage's share in the state of ''high'' to ''low'', no hazard is caused to the terminal 13 to be a constant level, and no hazard is caused to the terminal 16.
