OUTPUT CIRCUIT AND OUTPUT CONTROL SYSTEM |
摘要 |
An output circuit which outputs an output signal based on an input signal from an output terminal and brings the output terminal into a high impedance state in response to an impedance control signal. The output circuit includes an output pMOS transistor connected at a source thereof to a first power supply. The output circuit includes an output nMOS transistor connected between a drain of the output pMOS transistor and ground. The output circuit includes an output terminal connected between the drain of the output pMOS transistor and a drain of the output nMOS transistor. The output circuit includes a first level shifter circuit which outputs a first gate control signal from a first gate control terminal to control on/off of the output pMOS transistor. The output circuit includes a second level shifter circuit which outputs a second gate control signal from a second gate control terminal to control on/off of the output nMOS transistor. |
