Abstract

PURPOSE:To prevent the ringing of a data-out by changing successively a second data-out low level control signal from a low level to a high level, from the high level to the low level, and from the low level to the high level so on, when the data-out changes from the high level to the low level. CONSTITUTION:When a data-out terminal Dout comes from the high level to the low level, a transistor(TR) Q3 is turned ON once by the second data-out low level control signal from a data-out low level control circuit 5. Then, a speed, at which the data-out terminal Dout is made form the high level to the low level, is quickened, but afterwards, the TR Q3 is turned off, and the charge of an output load capacity C1 comes to be discharged only through the TR Q2. After a while, the TR Q3 is turned on again, and the TRs Q2 and Q3 maintain an output current. Thus, by turning off the TR Q3 at the time that the output causes the ringing, the ringing can be prevented.
