72V71643BC

The 72V71643BC three-to-eight line signal switch is an ideal fit for logic and signal control applications, especially those in the telecommunications sector. From multiplexer networks to decoders for voice-over-data conversion, the 72V71643BC delivers reliable switching performance and power efficiency.

Overview

The 72V71643BC is an integrated circuit (IC) used to switch digital or analog signals between three to eight different lines. The three input lines are labeled A, B and C and action can be triggered by a logic-level signal or by an explicit command. These signals then pass through the IC and are routed to one of the remaining eight output lines.

Application Fields

The 72V71643BC is a general purpose switch as it is suited to a variety of applications ranging from signal multiplexing to data flow control. It is a popular solution for multiplexers, decoders and other digital signal control circuits. Some specific applications include:

• Voice-over-data multiplexers in storing and routing telephone calls
• Data multiplexers which work between computer equipment components
• Digital circuit boards to control peripheral devices from a central processor
• Signal control for digital television and radio broadcasters
• Audio and video signal control for multimedia systems

Working Principles

The 72V71643BC is based on a triple 2-to-8 line decoder architecture, meaning that three separate 2-to-8 line decoders are combined within the single integrated circuit. The A and B lines are decoded separately, while the C line is used to select the decoder channel. When the C line is released, the input signals are then routed in a sequential order to one of the eight output lines.

The 72V71643BC delivers three separate two-way paths for signal buffering and routing. This, in turn, offers the user a variety of switching and control possibilities. As the IC contains its own power supply (Vdd), no external power is required in order to achieve a power efficient design.

Conclusion

The 72V71653BC three-to-eight line signal switch is an ideal fit for a variety of logic and signal control applications. From voice-over-data multiplexers to digital circuit boards, the 72V71643BC delivers reliable switching performance and power efficiency.
