Abstract
A plurality of MOSFET switches, one per bus line, are used to solve the problem of interfacing between two incompatible devices via a single shared bus. The MOSFET switches used are simple, inexpensive, and very fast. The switches perform two primary functions: 1) isolation of two bus sections (possibly for loading reasons); and 2) translation of incompatible voltages transmitted over the bus.
