ON Semiconductor MC74AC157DTR2 Multiplexer

The MC74AC157DTR2 is a high-performance, quad 2-input multiplexer from ON Semiconductor, designed to provide exceptional data selection to communication and computing applications. This device is part of the advanced high-speed CMOS (AC) family, which is renowned for its robust operation and compatibility with a wide range of digital systems.

With its four identical 2-input multiplexers, the MC74AC157DTR2 is capable of directing the flow of digital signals from multiple sources to a single output line. Each multiplexer has two input lines (A and B), one output line (Y), and a common select input (S). The select input determines which of the two data inputs is passed through to the output. When the select input is held low, the A input is enabled and passed to the output. Conversely, when the select input is high, the B input is selected.

The MC74AC157DTR2 features a wide operating voltage range of 2V to 6V, which makes it suitable for interfacing with both TTL and CMOS logic levels. This versatility ensures that the device can be used in a variety of digital environments without the need for additional level-shifting hardware.

ON Semiconductor has designed the MC74AC157DTR2 with a high degree of speed and reliability in mind. The device boasts fast switching times and low power dissipation, which are essential characteristics for modern digital circuits where efficiency is paramount. Additionally, the multiplexer's outputs can drive up to 10 LSTTL loads, providing the necessary drive capability for most applications.

The MC74AC157DTR2 is available in a TSSOP-16 package, which is a space-saving option for designs where board real estate is at a premium. It is also provided in tape and reel packaging, facilitating easy integration into automated manufacturing processes and making it an excellent choice for mass production requirements.

In summary, the MC74AC157DTR2 from ON Semiconductor is a versatile and efficient solution for digital signal routing in a wide array of applications. Its compatibility with multiple logic levels, low power consumption, and space-efficient packaging make it an ideal choice for designers looking to optimize their digital systems.
