SN74ALS251N Description

Short technical summary and product information.

The SN74ALS251N is a digital multiplexer from Texas Instruments, designed to select one-of-eight data sources using full binary decoding. This component features controlled complementary 3-state outputs, enabling direct interfacing with system buses. The 3-state outputs allow the device to drive data lines in bus-organized systems, with the ability to disable outputs to a high-impedance state.

 

Operating from a single 4.5V to 5.5V supply, the SN74ALS251N is characterized for operation over a temperature range of 0°C to 70°C. It is housed in a 16-PDIP package, suitable for through-hole mounting. The device provides complementary outputs for both true and inverted data, and its outputs are controlled by an output-enable (OE\) input.
