The FST3126MTCX is a logic-signal switch, also known as a multiplexer, decoder and single flip-chip, specializing in the field of logic-signals applications. This specialized switch and multiplexer offer a wide range of features, and a unique combination of high performance, accuracy and low power consumption.

This switch is comprised of 11 digital PSR-13–17/18T-type flip chips, as well as a 3-bit encoding decoder, which can be used in various applications. It provides up to eight input channels and can be used to switch logic-signal indicators between multiple inputs. The FST3126MTCX switch is designed to operate at 1.2V and 3.3V logic levels and operates at a maximum frequency of 140 MHz.

Its CMOS transistor structure provides a low power consumption of 1.56mA at 1.2V and 1.8mA at 3.3V, making it one of the most energy-efficient switches on the market. In addition, its low R_DSon of maximum 25Ω at 1.2V and 6Ω at 3.3V provides very low signal distortion when operating.

The FST3126MTCX offers three different select configurations, each providing up to eight input channels that can be selected. The switch has two internal registers, one for each input, which is used to store the active multiplexer settings. These user-programmable registers provide quick and accurate selection of the active input, with no additional setup required.

The FST3126MTCX can also be used as a decoder in logic gates. Its internal decoder uses 3-bit encoding to decode the input signals and can provide up to 8 output channels depending on the application. The logic gate can be used to switch the active input, based on the logic gate output.

The FST3126MTCX switch is ideal for use in applications where quick and precise selection of multiple inputs is needed. Its low power consumption and high frequency operation make it a great choice for high speed applications, while its low R_DSon ensures low distortion signals. Its multiplexer and decoder functions are invaluable in applications requiring precise selection of logic-signals, making it an excellent choice for a variety of logic-signal applications.
