Low power digital input circuit |
摘要 |
An input circuit for minimizing power consumption in connected circuits is implemented. The input buffer has a saturating amplifier with a gain greater than unity, which provides for rapid transition of slowly rising or slowly falling inputs, thereby minimizing the time interval of the cross conduction range. The input buffer also has a current source which provides a constant current that limits the current when the input is within the cross conducting range. This invention is especially useful for inputs which are slowly falling or rising, where connected output circuits may be in the cross-conducting range for extended periods. <IMAGE> |
