Application of level translator in admixture voltage logical system design

From the actual development project, this paper analyzed the logi c level unmatched matters between 5V system and 3.3V system when they communicated with each other. To solve these matters, it discussed how to utilize the level translators to realize signal input/output logic level compatibility between the different power voltage system, and also introduced the design principles and o verall plan about level translators. By use of level translators, it made the si gnal transmission reliable and could well solve the port compatible question of mix voltage logical system.
