ON Semiconductor MC74LVX157DTR2: Multiplexer IC

The MC74LVX157DTR2 is a high-performance quad 2-input multiplexer from ON Semiconductor, designed for use in applications that require routing of two different input signals to a single output. This integrated circuit (IC) is part of the LVX family, which is characterized by low-voltage operation and is optimized for 3.3V power supply systems, although it can operate with a voltage range from 2V to 3.6V.

Constructed with advanced silicon-gate CMOS technology, the MC74LVX157DTR2 offers high-speed operation while maintaining CMOS low power dissipation. It features a high impedance state during power down, which significantly reduces power consumption. The multiplexer's inputs tolerate voltages up to 5V, making it suitable for mixed-voltage applications and enabling it to interface with TTL logic levels.

The device has four individual 2-input multiplexers with common select and enable inputs. The select input determines which of the inputs (A or B) is connected to the output. When the enable input is high, all four multiplexers are turned off and the outputs are in a high impedance state, which is useful for implementing bus-oriented systems.

The MC74LVX157DTR2 is available in a TSSOP-16 package, ensuring a compact footprint on the PCB while providing good thermal performance. The package is designed for surface-mount technology (SMT), which makes it suitable for automated assembly processes and high-density circuit designs.

Key features of the MC74LVX157DTR2 include:

• Low-voltage operation: 2V to 3.6V
• High-speed performance: t<sub>PD = 4.8ns (max) at V<sub>CC = 3.3V
• Low power dissipation: I<sub>CC = 2μA (max) at T<sub>A = 25°C
• 5V tolerant inputs
• Pin and function compatible with other standard logic families
• Latch-up performance exceeds 300mA
• ESD performance: HBM > 2000V; Machine Model > 200V

ON Semiconductor's MC74LVX157DTR2 is ideal for a wide array of applications, including data routing, signal gating, and communication systems, where low power operation and high-speed performance are critical. Its robust design and industry-standard packaging make it a versatile choice for designers looking to optimize their high-performance digital systems.
