ON Semiconductor MC74LCX157DR2 Quad 2-Input Multiplexer

The MC74LCX157DR2 is a high-performance, quad 2-input multiplexer integrated circuit from ON Semiconductor, designed to function with a 2V to 3.6V VCC supply voltage range, while maintaining compatibility with 5V TTL logic signals. This component is part of the LCX family, which is renowned for its low voltage operation and low power consumption, making it an excellent choice for battery-operated and portable devices where power efficiency is crucial.

The device features four individual 2-input multiplexers with common select and enable inputs. Each multiplexer has two input lines (A and B), one output line (Y), a select input (S), and an output enable input (OE). The select input determines which of the two inputs (A or B) is routed to the output. When the output enable (OE) input is low, the selected input is passed to the corresponding output. If OE is high, the output of the multiplexer is in a high impedance state, effectively disconnecting it from the circuit, which is useful for bus-oriented systems.

With its 5V tolerant inputs, the MC74LCX157DR2 can be used in mixed-voltage environments, interfacing seamlessly with both 3.3V and 5V logic levels. This feature simplifies the design of multi-voltage systems and enhances the flexibility of the device in various applications. The multiplexer operates at -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

The MC74LCX157DR2 comes in a space-saving 16-pin SOIC package, making it a compact solution for high-density applications. Its fast propagation delay and low quiescent current are key attributes that contribute to its efficiency and speed, making it well-suited for high-speed data transmission and switching applications.

Whether you're designing telecommunications equipment, computing devices, or complex digital systems, the MC74LCX157DR2 from ON Semiconductor offers a combination of power efficiency, high-speed operation, and compatibility with existing 5V systems, making it a versatile and reliable choice for your multiplexing needs.
