ABSTRACT:
A universal input/output buffer uses all digital-type components, can be included on an integrated circuit chip and operates in a mixed voltage, multi-rail, power supply environment. The input/output buffer includes a multi-stage driver section and a sequencing section. Several types of sequencing techniques are used to control a plurality of driver stages and provide a combination of multiple firing schemes. In addition, other control techniques are employed such as full and partial feedback, sequential turn on/turn off of driver stages, and controlled introduction of a small amount of "crow bar" current.
