ABSTRACT:
An integrated circuit output driver system includes a first power line channel extending along the integrated circuit. The first power line channel includes a first power supply voltage line and a first ground voltage line. A second power line channel also extends along the integrated circuit and is spaced apart from the first power line channel. The second power line channel includes a second power supply voltage line and a second ground voltage line. A plurality of output drivers are located between the first and second spaced apart power line channels. Each output driver includes an output node, a pull-up circuit which pulls up the output node in response to a pull-up input signal, and a pull-down circuit which pulls down the output node in response to a pull-down input signal. The power supply and ground voltage connections for alternating output drivers are supplied by the first power supply voltage line and the second ground voltage line, and the second power supply voltage line and the first ground voltage line respectively. Switching noise on the power lines may thereby be reduced.
