The 74LVX138MX is a high-speed low voltage 1-of-8 decoder/demultiplexer designed for efficient address decoding in high-speed bipolar memory applications. It features three binary weighted address inputs (A0, A1, A2) and provides eight mutually exclusive active-Low outputs (O0 to O7) when enabled. The device includes three enable inputs, with two active-Low (E1, E2) and one active-High (E3), allowing for flexible operation as a demultiplexer. This component supports input voltage level translation from 5V to 3V, making it suitable for low power and low noise 3.3V applications. The LVX138 can be expanded to create larger decoders, such as a 1-of-24 decoder using three devices or a 1-of-32 decoder with four devices and one inverter. It operates within a temperature range of -40¬8C to +85¬8C and is available in multiple package types, including SOIC and TSSOP. The device is characterized by guaranteed simultaneous switching noise levels and dynamic threshold performance, ensuring reliable operation in various applications.
