Abstract: An integrated circuit comprises a microprocessor for generating data signals along a data bus by way of an inverter to a plurality of input/output switching buffers. The buffers pass the data signals to a transmission bus for onward transmission to a receiving integrated circuit. A respective drain and source supply power to the buffers. A transition checking circuit monitors the number of data signals on the data bus simultaneously switching from a first to a second logic state and a control circuit counts the number of the simultaneous switching data signals and generates a flag signal when the count exceeds half the number of buffers. The flag signal is applied to the inverter to invert all of the data signals on the bus.

Abstract: Voltage level shifting circuits have circuit devices coupled across sourcing output transistors to improve the switching speed of the low voltage to high voltage output transition. These circuit devices permit sourcing and sinking output transistors to be sized for optimal switching speed of the high voltage to low voltage output transition.

Abstract: Techniques of increasing drive strength and reducing propagation delays of a digital logic circuit through the use of feedback are presented. Logic circuitry operative to receive an input signal of the digital logic circuit and a delayed version of an output signal of the digital logic circuit turns “ON” a supplemental drive transistor for a digital state transition of the output signal. The supplemental drive transistor provides supplemental drive current to the digital logic circuit during the output signal digital state transition, thus advantageously reducing propagation delay and increasing fan-out capability. The logic circuitry turns “OFF” the drive transistor once the output signal digital state transition is complete.
