Abstract
The bidirectional driver circuit for PCI bus system involves minimal circuit outlay. It is manufactured in a 3.3 technology and is essentially also operated only with 3.3 V, but is suited for a 5 V signal environment. The driver circuit has at least one selection logic (AL), a control circuit (A), a p-channel MOS transistor (M113), a first, second and third n-channel MOS transistor (M110, M111, M112). The advantage of the driver circuit is in its minimal circuit outlay.
