Abstract

This patent application includes a description of a data bus interface apparatus which interfaces between one of a plurality of peripheral units (111) and a data bus (109). The data bus interface driver (243) is capable of biasing, data to the voltage level of the data bus (109), accepting data signals (233) having different amplitudes and is immune to differences in ground voltage potentials caused by induced noise and differing environmental conditions. The data bus interface driver (243) is capable of data transition rates in excess of 1 MHz and has low EMI and RFI emissions.
