The SJM185BXA is an input and output selector multiplexer and demultiplexer from New Japan Radio. This component is commonly used in telecommunications and audio visual applications to route digital or analog signals through one line and has become a basic component for set-top boxes, digital home appliances, and telecom terminals.The SJM185BXA operates in the range of 1.8V to 5.5V and is a member of Nippon’s AdvancedCMOS family of products. It has a wide range of applications because of its ultra-low power consumption and low power output capabilities. It is used to route and select digital and analog signals through one line and has become a basic component for set-top boxes, digital home appliances, and telecom terminals.

The SJM185BXA is an analog switch and a multiplexer/demultiplexer integrated circuit which functions in digital and analog systems. It is a versatile device that allow you to route analog or digital signals through just one line. There are 18 pins in this IC and is mainly split into 3 distinct groups: the 16 digital inputs, the output pin, and the digital enable pin. Depending on the digital enable and output, the device will select 1 of 16 digital inputs and enable it to pass through to the output pin. In doing so, the SJM185BXA will control the data between the digital inputs to the output. The enable pin is required for the device to function and is provided by the user logic.

The working principle of the SJM185BXA is simple and follows a set of highly defined functions. When enabled, it selects one of sixteen digital inputs and passes it to the output line. With the enable pin always low and the output pin high, it will route the data from the digital inputs to the output. When the enable pin is high and the output pin is low, the device is disabled and it holds the state of the last enabled input pin. The device also features a noise immunity circuit which is enabled by a single pin control resistor. This will help to reduce interference from any external noise and reduce the amount of errors due to noise. The SJM185BXA also has an integrated low-power operating mode which helps to reduce power consumption.

Among its most common applications, the SJM185BXA typically routes and selects digital and analog signals through one line and is used in set-top boxes, digital home appliances, and telecom terminals. It can also be used in industrial control systems, process control systems and consumer electronics. Additionally, it can be used in electronic test equipment such as oscilloscopes and spectrum analyzers. In each application, the role of the device is to select and route one of the sixteen digital inputs to the output pin.

In summary, SJM185BXA is used in various applications due to its ultra-low power consumption and low power output capabilities. It is an integrated circuit which serves as an analog switch and a multiplexer/demultiplexer. It operates in the range of 1.8V to 5.5V and can route and select digital and analog signals to a single output line. Common applications include set-top boxes, digital home appliances, telecom terminals, industrial control systems, process control systems, consumer electronics and electronic test equipment.
