The SN74LS251DR from Texas Instruments is a versatile 8-line to 1-line data selector/multiplexer designed for logic applications. This component features three-state outputs, allowing multiple devices to share a common bus without interference when disabled. It is fully compatible with most TTL circuits and performs parallel-to-serial conversion efficiently.
The device operates within a temperature range of 0 to 70°C, making it suitable for a variety of commercial applications. It is housed in a 16-pin SOIC (D) package, designed for surface mounting. The SN74LS251DR utilizes the LS TTL logic family, ensuring compatibility with other TTL devices in a system.
Key features include on-chip binary decoding to select one of eight data sources and a strobe-controlled output. The three-state output capability is crucial for bus-oriented systems, where the output can be enabled or disabled. The design minimizes the possibility of bus contention by ensuring faster disable times than enable times.
This multiplexer is ideal for applications requiring data selection, parallel-to-serial conversion, and interfacing with system buses. Its robust design and TTL compatibility make it a reliable choice for digital circuit design.
