ON Semiconductor MC74LVX257DG Quad 2-Input Multiplexer

The MC74LVX257DG is a high-performance, quad 2-input multiplexer designed by ON Semiconductor, a leader in energy-efficient innovations. This component is part of the LVX family of products, known for their low-voltage operation and interface capability with 5V logic levels. The MC74LVX257DG is ideal for applications requiring the selection of one out of two data sources for each multiplexer section.

The device operates at a voltage range of 2.7V to 3.6V, which allows for lower power consumption while maintaining the ability to interface with existing 5V systems. The low on-resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

Each multiplexer has two input sections, denoted as '0' and '1'. A separate enable input (G) is provided for each multiplexer. When the enable input is high, all outputs are in a high-impedance state, regardless of the other input conditions. This state of high impedance ensures that the outputs will neither load nor drive the bus line when the device is not selected. This feature is particularly useful for implementing bus-oriented systems where multiple devices can share a common output line.

The MC74LVX257DG is offered in a narrow-body SOIC-16 package, which is suitable for space-constrained applications. The packaging is also RoHS compliant, ensuring adherence to the latest environmental standards and regulations.

Key features of the MC74LVX257DG include:

• High-speed operation: t_PD 4.2 ns (max) at V_CC = 3.3V
• Low power dissipation: I_CC = 2 µA (max) at T_A = 25°C
• Power-down high impedance inputs and outputs
• ±24 mA output drive at 3.3V
• Multiple package options
• Pin and function compatible with other standard logic families
• Latch-up performance exceeds 300 mA
• ESD performance: HBM > 2000V; Machine Model > 200V

With its combination of performance and power efficiency, the MC74LVX257DG from ON Semiconductor is an excellent choice for a wide range of multiplexing functions in telecommunications, computing, and industrial electronic systems.
