Working Principles

The CY74FCT138CTSOCTE4 operates by taking a 3-bit binary input (A0, A1, A2) and decoding it to select one of the eight output lines (Y0-Y7). The enable inputs (E1, E2, E3) control the activation of each output line. When the appropriate input code is applied and the corresponding enable input is active, the selected output line becomes active, while all other output lines remain inactive.
