The AS1747-BTDT-1K is an elegant example of a type of switch known as an analog switch, multiplexer, and demultiplexer (ASMD). ASMDs are used in a wide range of applications, such as switching audio, video, and other circuits. The AS1747-BTDT-1K is a 4-pole, 3-position, break-before-make analog switch designed for applications requiring non-symmetrical switching.

Design Features

This device offers several design features. The break-before-make switching ensures that both poles of a switch are never energized at the same time, which prevents short-circuiting. The AS1747-BTDT-1K also has low power consumption thanks to low on-resistance, allowing a high degree of energy efficiency. Finally, its compact size makes it a suitable choice for space-constrained applications.

Applications

The versatility of the AS1747-BTDT-1K makes it suitable for a wide range of applications. It can be used in audio and video switching, such as in audio mixing consoles, surge protectors, and loudspeaker protection. It can also be used for motor controllers and switching of loads in dimming applications, as well as for monitoring and control switches in temperature and humidity sensors. The device can also be used to control solenoids and relays, as well as in telecommunications applications.

Working Principle

The AS1747-BTDT-1K works according to the principles of physics. Its design features a pair of electromagnetically driven switch contacts. When a voltage or current is applied to a pair of switch contacts, a magnetic field is created which causes the contacts to open or close. Depending on the direction of the current, the contacts will either open or close, thus creating a break before make switching action. This ensures that both switch poles are never energized at the same time and thus prevents short-circuiting.

Conclusion

The AS1747-BTDT-1K is a versatile and efficient analog switch, multiplexer, and demultiplexer that can be used in a wide range of applications. Its break-before-make design ensures that both switch poles are never energized at the same time, and its low power consumption makes it an energy-efficient choice. Its compact size makes it suitable for space-constrained designs and its robust construction ensures durability and reliability. As such, the AS1747-BTDT-1K is an excellent option for a variety of applications.
