Reduced switching noise output buffer using diode for quick turn-off |
摘要 |
A buffer characterized by a pull-up network and a pull-down network which are both coupled between an input and an output of the buffer. Each of the networks include a number of switch elements which can be sequentially turned on or off by means of an RC network to provide slew-rate control for the buffer. Preferably, each of the networks are associated with diode bypass networks to reduce crowbar current. In operation, both the pull-up network and the pull-down network turn on slowly but turn off very quickly due to the diode bypass networks.
