The 74AC138SC is a high-speed 1-of-8 decoder/demultiplexer manufactured by On Semiconductor. This integrated circuit is designed for applications such as high-speed bipolar memory chip select address decoding. It features multiple input enables for easy expansion, allowing for the creation of larger decoders.
The device accepts three binary weighted inputs (A0, A1, A2) and provides eight mutually exclusive active-LOW outputs (O0-O7). It includes two active-LOW enable inputs (E1, E2) and one active-HIGH enable input (E3). All outputs remain HIGH unless E1 and E2 are LOW and E3 is HIGH.
With an operating voltage range of 2V to 6V and an operating temperature range of -40°C to 85°C, the 74AC138SC is suitable for various environments. It features outputs that can source or sink 24 mA. The device is available in a 16-SOIC surface mount package, with dimensions of 0.154" width.
This decoder/demultiplexer can also be utilized as an 8-output demultiplexer by using one of the enable inputs as the data input and the others as strobes. Unused enable inputs must be permanently tied to their appropriate active-HIGH or active-LOW state.
