ON Semiconductor MC74HC157ADTR2: High-Performance Multiplexer

The MC74HC157ADTR2 is a high-speed quad 2-input multiplexer fabricated with silicon gate CMOS technology from ON Semiconductor. It possesses the low power consumption of standard CMOS integrated circuits, combined with the ability to drive 10 LSTTL loads. This multiplexer is a versatile component that is essential for a wide range of digital applications, including data routing, signal gating, and the selection of multiple input sources.

This device has four separate 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 outputs are forced to a low state regardless of the other inputs. This feature allows for easy parallel expansion of the multiplexer by connecting the enable inputs together. When the enable input is low, the normal multiplexing action takes place.

The MC74HC157ADTR2 is capable of operation with a wide range of supply voltages, from 2V to 6V, making it suitable for use in systems that require a high level of integration and low power consumption. Its fast switching speeds and low quiescent current make it an excellent choice for battery-powered devices.

Key features of the MC74HC157ADTR2 include:

• High Speed: Typical tPD of 13 ns at VCC = 5V
• Low Power Consumption: 20 µA maximum ICC
• High Noise Immunity: Characteristic of CMOS devices
• Functional Equivalency: Pin compatible with LS157
• Wide Operating Voltage Range: 2V to 6V
• Sourcing or Sinking: 4 mA at VCC = 5V

ON Semiconductor's MC74HC157ADTR2 comes in a TSSOP-16 package, which is suitable for automated assembly processes and space-constrained applications. This multiplexer is designed for multiplexing digital or analog signals and is an excellent choice for designers looking for a reliable and versatile switching solution.

Whether you are working on data acquisition systems, communication interfaces, or control circuits, the MC74HC157ADTR2 offers the performance and reliability that modern electronics demand. Its combination of high-speed operation, low power consumption, and robust noise immunity makes it a smart choice for your digital multiplexing needs.
