MC74LVX138: 3-to-8 Line Decoder

The MC74LVX138 is an advanced high speed CMOS 3-to-8 line decoder. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems. When the device is enabled, three Binary Select inputs (A0 - A2) determine which one of the outputs (O0 - O7) will go Low. When enable input E3 is held Low or either E2 or E1 is held High, decoding function is inhibited and all outputs go high. E3, E2, and E1 inputs are provided to ease cascade connection and for use as an address decoder for memory systems.
