DM74ALS257SJ

The DM74ALS257SJ is an IC component, specifically a quad 2-input multiplexer with tri-state outputs. It is a versatile and widely used integrated circuit available in the market. It provides a convenient solution for data routing and selection in various digital systems. Here are some of its key features: 1. Quad 2-Input Multiplexer: The DM74ALS257SJ integrates four high-speed 2-input multiplexers in a single package. Each multiplexer has two data inputs (A and B) and a select input (S). The select input determines which data input is routed to the output. 2. Tri-State Outputs: The outputs of the multiplexers are tri-state, which means they can be disconnected from the circuit, making them ideal for bus-oriented applications. When the tri-state control input (G) is high, the outputs are in a high impedance state, allowing multiple devices to share the bus without interference. 3. Wide Operating Voltage Range: The DM74ALS257SJ operates within a wide voltage range, typically from 4.5V to 5.5V. This makes it compatible with various digital logic families, including TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor). 4. Fast Switching Speed: The IC offers a fast propagation delay (typically around 9ns), enabling high-speed data routing and selection, crucial for time-critical applications
