The 74ACT157SCX is a versatile quadruple 2-input multiplexer IC (Integrated Circuit) component designed for high-speed digital applications. It is a part of Texas Instruments' 74ACT series, which is known for its compatibility with both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) input and output voltage levels. The 74ACT157SCX offers multiple features that make it ideal for various multiplexing applications in electronic circuits.
Key Features of the 74ACT157SCX:
1. Quad 2-input Multiplexer: The IC includes four independent 2-input multiplexers, allowing the selection of one out of four data inputs.
2. Multiplexer Operation: The active-low Enable (E') input controls the IC's operation. When E' is low (logic 0), the selected data input passes through to the output; otherwise, the output remains in a high-impedance state.
3. Fast Switching Speed: The 74ACT157SCX has a fast propagation delay time of only 3.5 nanoseconds, making it suitable for high-speed digital circuits.
4. Wide Operating Voltage Range: It operates with a supply voltage (VCC) range of 4.5V to 5.5V, providing compatibility with both TTL and CMOS voltage levels
