The PI3B16211A is an intelligent, low-power Signal Switch with 1:2 multiplexing capability for single-ended signals. It has been designed for the demands of portable applications in which the smallest package sizes and low power is paramount.

The PI3B16211A contains a single 1:2, high performance, low-voltage switch. It can be used as a multiplexer, decoder, or as a signal switch to provide flexible, low-power signal routing. Through a two-bit input, the logical signals determine which of two pins is connected to the output pin.

The PI3B16211A has integrated protection logic to guard against damage due to over- and under-voltage on either input pin, as well as overvoltage on the output pin. It can switch up to 1.8V differential signal levels with minimal signal degradation, and is usually specified for up to 2.5V rail. The outputs can be powered from a separate supply of up to 5.5V.

The PI3B16211A is designed for applications in which minimum package size, the lowest power consumption, and protected signal routing is desired. It is ideal for power sensitive applications such as mobile phones, PDAs, and other mobile and embedded applications.

The PI3B16211A works on the principle of signal routing. A two bit binary input is used to control the routing of a signal. When the two bit input is “00”, the signal is connected to Pin 1 of the PI3B16211A. When the two bit input is “01”, the signal is connected to Pin 2 of the PI3B16211A. Any other combination of the two bit inputs will cause the signal to be disconnected from the output pin. The PI3B16211A is configured such that the protection circuitry is enabled when either Pin 1 or Pin 2 is inactive.

The PI3B16211A is ideal for applications in a variety of signal routing and multiplexing applications. It is used in cellular phones and other portable devices for signal switching, multiplexing, and decoding. It is also used in embedded applications for routing signals between multiple devices. It can be used for signal level shifting and signal conditioning. The PI3B16211A is widely used in system designs requiring reliable operation, low power consumption, and minimal packaging size.

In summary, the PI3B16211A is a low-power Signal Switch with 1:2 multiplexing capability suited for portable and embedded applications in which the smallest package sizes and low power consumption are crucial. Through a two-bit input, the logical signals determine which of two pins is connected to the output pin. It is widely used for signal routing, multiplexing, and decoding applications. It is also used in embedded systems for signal level shifting and signal conditioning.
