<p>PURPOSE:To match the variance of transmission delay time owing to IC manufacture variance to a desired value by connecting a serial circuit consisting of a control resistance and a control diode to a pull up resistance in parallel. CONSTITUTION:The serial circuit consisting of load circuits RL1 and RL11 and current control elements D1 and D2 which are connected in parallel and in which a conductive state can be controlled from an external part is provided and the variable control of continuous transmission delay time tpd is attained by a control signal voltage V6 given to a control terminal C.</p> |
