Title: Buffer circuit having
Inventor: UIRIAMU KEI PETEI
IPC: H03K17/16
Filed: 1989-10-23
Abstract: PURPOSE: To suppress the di/dt noise levels of a power supply line and a ground line by limiting a sudden change in an output buffer circuit in response to a feedback signal. CONSTITUTION: The buffer circuit is provided with a field effect transistor(FET) 3 for driving an output pad 2 at the time of receiving a high speed switching signal 'data in' and the FET 3 is provided with a through rate limiting feedback capacitor or a capacitor 7 connected between its source electrode 4 and control gate electrode 6. When a data-in signal is turned to a low level and the voltage of the pad 2 is dropped lower than about a half of power supply voltage, an OR gate 14 enables a transistor(TR) 16 to pull up a node 9 to power supply voltage VDD. Thus the di/dt of an output signal is controlled, the sufficiently large pull-up of the output stage after transition is guaranteed and instantaneous current supplied to large capacity load is limited. Consequently the noise spike (di/dt) of ground and power supply lines can be reduced.
