The MC74VHCT157ADR2 is a high-performance, quadruple 2-input multiplexer from ON Semiconductor, designed to provide users with a versatile and reliable solution for routing digital signals in their electronic systems. This advanced multiplexer is part of the VHCT (Very High-Speed CMOS TTL-Compatible) family, which is known for its high-speed operation while maintaining CMOS low power dissipation.

This device integrates four individual 2-input multiplexers into a single package, each capable of selecting one of two inputs to pass through to the output. It features a common select input and an enable input for all four multiplexers, allowing for convenient control and flexible use in a wide range of applications, including data routing, signal gating, and function generation.

The MC74VHCT157ADR2 operates over a broad voltage range from 2V to 6V and is TTL-compatible when operated at VCC = 5V. The low on-resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. This makes the device particularly suitable for interfacing with high-speed microprocessors and microcontrollers in systems where minimizing signal distortion is critical.

Features of the MC74VHCT157ADR2 include:

• High-speed performance: tPD = 5.3 ns (typ) at VCC = 5V
• Low power dissipation: ICC = 2 μA (max) at TA = 25°C
• High noise immunity characteristic of CMOS devices
• Pin and function compatible with other standard logic families
• Outputs can drive up to 10 LSTTL loads
• Multiple package options available

Enclosed in a slim SOIC-16 package, the MC74VHCT157ADR2 is optimized for improved PCB space utilization and enhanced thermal performance. Its robust design ensures reliable operation even in challenging environmental conditions, making it an ideal choice for industrial, automotive, and consumer electronics applications.

Whether you're designing a complex digital system or simply need a high-quality multiplexer for signal routing, the MC74VHCT157ADR2 from ON Semiconductor offers the performance, flexibility, and reliability needed to meet the demands of modern electronic designs.
