The DS1884AT+ series is an 8-bit, serial-bus, dual-channel analog multiplexer/switch family designed for industrial and commercial applications. It features two ex- ternal switching channels, each channel with eight available states. The DS1884AT+ enables applications such as signal routing, signal conditioning, signal acquisition, and signal gating. Furthermore, it can be used as a multiplexer, a demultiplexer, and a data selector.

The DS1884AT+ family provides several options for inter-facing with microprocessors, microcontrollers, digital signal processors and other digital I/O devices. All members of the family support a state/status register for fast detection of the switch status and an interrupt signal for notifying an external processor upon change of state. This makes the DS1884AT+ an ideal component for industrial and consumer applications.

Application Fields

The most obvious application of the DS1884AT+ series is signal routing and signal conditioning. By properly configuring the dual-channel analog multiplexer, signal inputs can be selected, reordered, amplified and even filtered. Likewise, signal output chains can be similarly configured and multiplexed. This makes the DS1884AT+ an excellent low-cost solution for device signal acquisition, signal gating and signal routing.

Other industrial and consumer applications include light and sound control, force and temperature sensing, automatic testing, automation control and data conversion. With its two external channels and its fast response time, the DS1884AT+ can be used in applications where precise control and quick switching is required. It is also perfect for applications which require higher levels of system integration and where precise switching control is required.

Working Principle

The DS1884AT+ family operates by using two external channels which are connected to the system microprocessor, controller or other digital input/output devices. Each channel can have up to eight available states, which are controllable by using a special state/status register. The register is used to set the desired switching state and can be updated in real time with a single write cycle. Additionally, an interrupt signal can be provided when the state/status register changes.

Once the desired channel state is set, the DS1884AT+ is capable of switching channels with fast response speed. The switching time can be as low as 50ns, which makes it great for applications requiring real-time performance. Furthermore, the low standby current consumption makes it ideal for applications which require long battery life.

The DS1884AT+ family is also capable of storing multiple switching settings which can be useful for many industrial applications. This is done by using additional state/status registers which can be read and written in real time. This makes the DS1884AT+ ideal for applications which require fast and precise channel switching.

Conclusion

The DS1884AT+ series is a versatile dual-channel analog multiplexer/switch designed for industrial and commercial applications. It features two external switch channels each with up to eight available states. The family provides several options for inter-facing with microprocessors, microcontrollers, digital signal processors and other digital I/O devices. It is capable of switching channels with fast response speed, making it ideal for applications requiring real-time performance. Additionally, the DS1884AT+ family is capable of storing multiple switching settings which can be useful for many industrial applications.
