Bus settle time by using previous bus state to condition bus at all receiving locations

摘要: An I/O bus interface cell includes a driver circuit having an input terminal fed by logic signal and output to produce in response thereto drive selectable rise fall time characteristics accordance with reference voltage provided the driver. The also receiver coupled said of disposed latch unresolved, unamplified received prior resolving state signal. further termination connected driver, impedance characteristic at terminal, being circuit. Preferably, circuits are fabricated on common semiconductor substrate.
