LOGIC SWITCH IN DIGITAL DESIGN

Описание: A logic switch is a manually operated or automatically controlled electrical device used to apply either a logic HIGH or logic LOW signal to a digital circuit. It function by establishing or interrupting a conductive path between the input node and the reference voltage - typically Vcc for a HIGH state or ground for a LOW state. Logic switches serve as fundamental input mechanisms to influence the state of a logic circuit. Ther output must be stabilized with supporting components such as pull-up or pull-down resistors to prevent undefined or floating logic levels.
