ABSTRACT:
A low voltage pull-down circuit for maintaining a node at a logic LOW voltage is provided. When a logic LOW is desired, the circuit provides a low-impedance path from the node to ground. The node may be easily pulled-up to a logic HIGH voltage, for example, by simply removing the low-impedance path and allowing a voltage source to reach the node through a resistor or transistor.
