Working Principles

The SN74LVC157APWRG4 is a quad 2-line to 1-line data selector/multiplexer. It selects one of the four input lines (A1, A2, A3, B3) based on the select inputs (B1, B2). The selected data is then presented at the output (Y1, Y2, Y3, Y4). The non-inverting outputs ensure that the output data matches the input data.

The IC operates within a wide supply voltage range of 1.65V to 5.5V, making it compatible with various logic families. It utilizes high-performance CMOS technology, which enables low power consumption and fast switching speed. The Schmitt-trigger inputs provide noise immunity, ensuring reliable operation in noisy environments.
