DM54LS138J/883

The DM54LS138J/883 is an integrated circuit (IC) component that belongs to the DM54LS series of integrated circuits, manufactured by National Semiconductor. This particular IC is a 3-to-8 line decoder/demultiplexer and has several key features that make it useful in various digital applications. Here are some of the important features of the DM54LS138J/883: 1. Decoding Function: The DM54LS138J/883 can decode a 3-bit binary address to one of the eight outputs. This makes it crucial in applications that require a high number of input combinations but a reduced number of output lines. 2. TTL Compatibility: The IC is designed with TTL (transistor-transistor logic) compatible inputs, which means it can operate seamlessly with other TTL logic devices. 3. Low Power Consumption: The IC is designed to operate with low power consumption, making it suitable for battery-powered applications or any other scenario where power efficiency is vital. 4. Fast Operation: The DM54LS138J/883 offers high-speed operation with a propagation delay of only 13 ns (typical). This ensures quick and efficient decoding of the input signals. 5. 3-State Outputs: The IC provides 3-state outputs, which means the outputs can be either active low or in a high-impedance state. This feature allows for convenient connection to other devices or bus systems
