SN74AS158DRG4 Quad 1-of-2 Data Selector/Multiplexer from Texas Instruments

The SN74AS158DRG4 is a high-performance integrated circuit designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This device is a quad 1-of-2 data selector/multiplexer that offers a significant speed advantage when compared to other standard logic multiplexers. It is particularly suitable for applications requiring the selection or routing of data from two sources to a single output.

Each multiplexer in the SN74AS158DRG4 has two select inputs (A and B), four data inputs (1A0, 1A1, 1B0, 1B1), and two outputs (1Y, 2Y). The device operates by selecting one of the two binary inputs for each multiplexer, based on the combination of the select inputs, and routing it to the corresponding output. This functionality is essential for data manipulation in various digital systems, including computers, communication devices, and signal processing equipment.

The SN74AS158DRG4 comes in a slim SOIC-16 package, which is ideal for space-constrained applications. It operates over a wide range of supply voltages from 4.5V to 5.5V, making it compatible with standard TTL logic levels. The device also features a typical propagation delay time of 3 ns, ensuring high-speed operation for time-sensitive applications. Additionally, it has a low power consumption, which is beneficial for power-sensitive designs.

This multiplexer is designed with Texas Instruments' Advanced Schottky (AS) technology, which provides a perfect balance between speed and power consumption, resulting in excellent performance. Furthermore, the SN74AS158DRG4 has a wide operating temperature range of -40°C to 85°C, which guarantees reliable operation under extreme conditions.

Applications for the SN74AS158DRG4 include, but are not limited to, data routing in digital systems, signal gating, function generation, and logic implementation. Its high-speed and low-power characteristics make it an excellent choice for designers looking to optimize their digital systems for performance and efficiency.
