Functional DescriptionFunctional Description Low-Voltage 3-to-8 Line Decoder with 5-V Tolerant Inputs and Outputs 2. 2. 2. 2. GeneralGeneralGeneralGeneral The 74LCX138FT is a high-performance CMOS 3 to 8 decoder. 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. When the device is enabled, 3 binary select inputs (A, B and C) determine which one of the outputs (Y0-Y7) will go low. When enable input G1 is held low or either G2A or G2B is held high, decoding function is inhibited and all outputs go high. G1,G2A, and G2B inputs are provided to ease cascade connection and for use as an address decoder for memory systems. All inputs are equipped with protection circuits against static discharge. 3. 3.
