5V compliant transmission gate and the drive logic using 3.3V technology

摘要

The logic gate has at least one input terminal in which a digital input signal is applied having two possible logical signal values and at least one output terminal to output an output signal having a logical signal values. Two different logical voltage levels are allocated to both possible logical signal values of the output signal and a logic circuit is provided between the input and the output terminals. The logic circuit has several switching elements, especially switching transistors, working or produced according to the logical voltage level. The logic circuit is supplied with a supply potential that exceeds the logic voltage level. The logic circuit has at least two switching elements, especially switching transistors, in the output path allocated to the output terminal.
