Abstract
PURPOSE: To decrease the number of the step of the output driving circuit and thus to reduce the delay time for the master sliding system IC containing the gate array by connecting in parallel two units of the final step gate of the IC internal logic circuit which is connected to the input terminal of the output driving circuit.
CONSTITUTION: Output driving circuit 110 consists of the push-pull circuit using the MOS transistor and the inverter, and the gate to be connected to input terminal 101 of circuit 110 is composed of the parallel circuit of logic gate 109a and 109b. And the signal featuring the opposite phase to the input signal is produced at output terminal 102. Thus, two units of the gate are put in parallel to cause no difference from the conventional constitution for the push-pull circuit comprising enhancement- type MOS transistor 105 and 106 to be provided to circuit 110. But only one unit of inverter 108 suffices for the preamplifier which is connected to the push-pull circuit. As a result, the number of the step can be decreased with the reduced delay time.
