应用须知
- Bus-Hold CircuitPDF, 418 Kb, 档案已发布: Feb 5, 2001
When designing systems that include CMOS devices, designers must pay special attention to the operating condition in which all of the bus drivers are in an inactive, high-impedance condition (3-state). Unless special measures are taken, this condition can lead to undefined levels and, thus, to a significant increase in the device?s power dissipation. In extreme cases, this leads to oscillation of
