ON Semiconductor MC74HC157AN Quadruple 2-Channel Multiplexer

The MC74HC157AN is a high-performance, silicon-gate CMOS device from ON Semiconductor that serves as a quadruple 2-channel multiplexer. This integrated circuit is designed to select one of two data sources for each output channel, controlled by a common select input. It is a versatile component commonly used in digital systems for routing signals and combining multiple data sources.

This multiplexer features four identical 2-channel multiplexers, each with its own set of inputs, outputs, and enable pin. The enable pin acts as an active low control, allowing the multiplexer to be turned off and preventing any data from passing through. When the enable pin is low, the selected input data is passed through to the output. The common select input determines which set of data inputs (A or B) is connected to the corresponding outputs for all four multiplexers.

The MC74HC157AN operates over a wide voltage range from 2V to 6V and offers low power consumption, making it suitable for battery-powered devices and other low-power applications. Its high noise immunity and low power dissipation are consistent with the MOS technology used in its design.

This device is compatible with the TTL family and can drive up to 10 LSTTL loads. The fast switching speeds and balanced propagation delays are key features that make the MC74HC157AN suitable for high-speed data processing and communication systems. It is provided in a 16-pin DIP (Dual In-line Package), which is easy to handle and integrate into a wide range of electronic circuits.

Applications for the MC74HC157AN include signal gating, data routing, multiplexing of digital signals, function generation, and many other logic-based operations. Its robust design and ON Semiconductor's commitment to quality ensure reliable performance in a variety of demanding applications.

Overall, the MC74HC157AN is a practical and efficient solution for designers looking to manage multiple data streams within their digital systems, offering both versatility and reliability in a compact form factor.
