ON Semiconductor MC74LCX257DTR2G Quadruple 2-Input Multiplexer with 5V Tolerant Inputs

The MC74LCX257DTR2G is a high-performance, CMOS quad 2-input multiplexer with 5-volt tolerant inputs, designed for use in systems that require low power consumption and high noise immunity. Manufactured by ON Semiconductor, this multiplexer is part of the LCX family which is known for its capabilities to interface with 5V systems while operating at a lower voltage, thus providing a bridge between two different voltage domains.

This device features four individual 2-input multiplexers with common select and enable inputs. Each multiplexer has two data inputs (A and B), one output (Y), a select input (S), and an enable input (OE). The select input determines which of the data inputs is passed through to the output, with the output being disabled when the enable input is high. This functionality makes the MC74LCX257DTR2G versatile for routing and controlling data flows in various digital systems.

With its 5V tolerant inputs, the MC74LCX257DTR2G can receive input signals from higher voltage logic levels without the need for additional level-shifting hardware, simplifying design and reducing component count. The device operates over a wide voltage range of 2.3V to 3.6V, allowing for use in low-voltage applications such as battery-powered devices, portable electronics, and energy-efficient computing systems.

The MC74LCX257DTR2G offers a robust design with high-speed performance. It is characterized for operation from -40°C to +85°C, making it suitable for industrial applications where temperature extremes are common. The device is provided in a TSSOP-16 package, which is ideal for space-constrained applications due to its small footprint.

Key features of the MC74LCX257DTR2G include:

• 5V tolerant inputs for interfacing with higher voltage logic levels
• Low power consumption for energy-efficient designs
• High noise immunity characteristic of CMOS technology
• Wide operating voltage range (2.3V to 3.6V)
• Industrial temperature range (-40°C to +85°C)
• Compact TSSOP-16 package

Overall, the MC74LCX257DTR2G from ON Semiconductor is an excellent choice for designers looking for a reliable and versatile multiplexer that bridges 5V and lower voltage logic while maintaining low power and high noise immunity.
