Functional DescriptionFunctional Description Low-Voltage Quad 2-Channel Multiplexer with 5-V Tolerant Inputs and Outputs 2. 2. 2. 2. GeneralGeneralGeneralGeneral The 74LCX157FT is a high-performance CMOS multiplexer. Designed for use in 3.3 V systems, it achieves high- speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) V applications, but it could be used to interface to 5 V supply CC environment for inputs. It consists of four 2-input digital multiplexers with common SELECT and ST inputs. When the ST input is held level, selection of data is inhibited and all the outputs become level. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. All inputs are equipped with protection circuits against static discharge. 3. 3.
