Abstract
A tristateable sense amplifier, for driving a bus directly with minimal size devices, includes a control transistor coupled to a reference voltage terminal and having a control electrode receiving a first control signal. A first series circuit includes a first transistor of a first channel type and a second transistor of opposite channel type coupled between the control transistor and a supply voltage terminal. A control electrode of the second transistor receives a first input signal and the second transistor generates a first output signal. A second series circuit includes a third transistor of the first channel type and a found transistor of the opposite channel type coupled between the control transistor and the supply terminal. A second input signal is coupled to the control electrode of the fourth transistor. A fifth transistor of the first channel type is coupled between the voltage supply terminal and the control electrodes of the first channel type transistors and has a control electrode coupled to receive a second control signal. A sixth transistor of the first channel type is coupled between the control electrodes of the first channel type transistors and a junction of the third and fourth transistors and has a control electrode coupled to receive a third control signal.
