74AC138SCX Description

Short technical summary and product information.

The 74AC138SCX is a high-speed 1-of-8 decoder/demultiplexer manufactured by On Semiconductor. This device is suitable for high-speed bipolar memory chip select address decoding. It accepts three binary weighted inputs (A0, A1, A2) and provides eight mutually exclusive active-LOW outputs (O0-O7) when enabled. The device features multiple input enables for easy expansion, allowing for parallel expansion to a 1-of-24 or 1-of-32 decoder configuration.

 

The 74AC138SCX operates with a supply voltage ranging from 2V to 6V and has an operating temperature range of -40°C to 85°C. Its outputs can source or sink up to 24 mA. The component is available in a 16-SOIC package, designed for surface mounting.

 

This decoder/demultiplexer can also be utilized as an 8-output demultiplexer by using one of the active-LOW enable inputs as the data input and the other enable inputs as strobes. Unused enable inputs must be permanently tied to their appropriate active-HIGH or active-LOW state.
