The 74LVC138APW is a 16-pin small-outline package (SOP) integrated circuit. It is a high-speed 3-to-8 line decoder/demultiplexer. This IC accepts three binary weighted address inputs (A0, A1, A2) and, based on these inputs, decodes them to activate one of the eight outputs (Y0 to Y7), with the remaining outputs being deactivated.
The device functions with three enable inputs (E1, E2, E3). E1 and E2 are active-low, meaning the IC is enabled when these inputs are low. E3 is active-high, meaning it is enabled when this input is high. The combination of these enable pins allows for cascading of multiple devices for decoding larger numbers of input signals. When the device is enabled, one of the eight outputs will be low, while the others remain high, corresponding to the binary value of the inputs A0 to A2. This makes the 74LVC138APW suitable for applications requiring decoding, demultiplexing, or memory address decoding.
