The FST33X257QSPX is a family of logic-signal switches, multiplexers, and decoders. This device family consists of three different devices, including a multiplexer (MUX), a switch array (SWC), and a decoder (DEC). Each device is optimized for low-voltage and low-power operation, making them ideal for use in portable and battery operated applications.

The FST33X257QSPX multiplexers are designed to switch one of many signals among multiple output ports. It is ideal for applications where multiple input signals need to be sent to the same destination. The MUX is available in both 8- and 16-bit configurations and features high-performance differential inputs and outputs that minimize the effects of noise and minimize the number of external components needed for the application. The MUX also provides exact voltage level shifting between the inputs and outputs and has a power-off mode for conservation when not in use.

The FST33X257QSPX switch (SWC) array is designed to route a signal from an input port to multiple output ports. The SWC is available in 4- and 8-bit configurations and is ideal for applications that require the routing of an input signal to multiple destinations. The high-impedance inputs and outputs are designed for low-power operation and the switch is powered down when not in use for maximum efficiency. Additionally, the low on-resistance and low ohmic variation of the switches provide high switching speed and linearity.

The third type of logic-signal switch in the FST33X257QSPX family is the decoder (DEC). The DEC is available in both 8- and 16-bit configurations and features high-speed decoding that is ideal for applications that require the decoding of an input signal into multiple outputs. The DEC uses low-power logic levels which makes it ideal for portable applications and it also features power-off mode for maximum power efficiency. Additionally, the DEC has a low maximum output impedance which allows it to drive its outputs with minimal glitches.

The FST33X257QSPX family of logic-signal switches, multiplexers, and decoders provide low-voltage and low-power operation for portable and battery-operated applications. The multiplexers are optimized for maximum noise reduction and minimal external components; the switch array is designed for low-power operation and high switching speed and linearity; and the decoder provides high-speed decoding and low maximum output impedance. Together, these devices provide a complete solution for applications requiring logic-signal switching, multiplexing, and decoding.
