Interface circuit for data processing system |
摘要 |
A data processing system which has an interface circuit that interfaces the data processing system to input devices. The interface includes an input means such as a pad for conducting signal levels from the interface devices to the data processing system. A digitizer, such as a Schmitt trigger, digitizes the signal levels to signal levels that are acceptable by the data processing system. An output line conditioner conditions the data lines that are connected to the digitizers to prevent overdriving of the data lines by the digitizers. Line drivers are used for driving the digitized system on the data lines throughout the data processing system.
