Title: Integrated buffer circuit
Inventor: BURAIAN MAAFUII
IPC: G06F3/00
Filed: 1993-09-16
Abstract: PURPOSE: To suppress an influence of a disturbance on a conductor by connecting the gate of an enable transistor TR to the enable input terminal of the buffer circuit. CONSTITUTION: When a first enable TR EN1 is in the conductive state and a second enable TR EN2 is in the cut-off state, a p-channel TR P1 of a first inverter I1 and a constant current source I are connected. Consequently, the buffer circuit doesn't sense the disturbance and the voltage fluctuation of a supply power VDD. It doesn't sense the disturbance of an input signal IN by limiting a switching point of the inverter I1 to a narrow area. Since the TR En1 is an n-channel TR and the TR EN2 is a p-channel TR, an enable signal OEN has a first logical level in an activated high level during the operation.  When the TR EN1 is in the conductive state and the TR EN2 is in the cur-off state, one signal determined by the input signal IN and scales of the inverter I1 and the constant current source I is given to a circuit nodal point 1 and is outputted as an output signal OUT by a second inverter I2.
