Logic circuit for performing e.g. OR operation in microprocessor, has control input, where clock signal provided over input determines if switching unit is opened or closed, and common connection is connected with earth if unit is closed

摘要

The circuit has a set of unidirectional circuit arrangements (5) that are arranged in a parallel manner with a switching unit (6). The switching unit is connected with a common connection of the unidirectional circuit arrangement and with an earth. A clock signal provided over a control input (ST) determines if the switching unit is opened or closed, where the connection is connected with the earth if the switching unit is closed.
