The 74LVQ138SCX is a 3-to-8 line decoder/demultiplexer integrated circuit (IC) component that is widely used in digital electronics applications. It belongs to the 74LVQ family of low-voltage quadruple-supply translating CMOS logic ICs. This IC provides a simple and efficient way to decode binary information and select one of the eight outputs based on the input.
Key features of the 74LVQ138SCX IC include:
1. Supply Voltage Range: This IC operates within a wide supply voltage range of 1.65V to 5.5V, making it suitable for use in both low-voltage and standard voltage applications.
2. High-Speed Operation: The 74LVQ138SCX is designed to provide high-speed operation, with a maximum propagation delay of 3.8 ns. This enables rapid decoding and demultiplexing of input signals.
3. Multiple Inputs: It offers 3 input lines (A0, A1, and A2) to select any of the 8 outputs (Y0 - Y7). The binary combination of these input lines determines the active output.
4. Active Low Outputs: The outputs of the IC are active low, meaning that when an output is selected, it becomes logic low (0V), while all other outputs remain logic high (default state)
