The 74HCT138DB118 is a high-speed, CMOS logic IC component that belongs to the 74HCT series. It is a 3-to-8 line decoder/demultiplexer, and it is commonly used in digital electronics applications. The IC is manufactured by Nexperia, a leading semiconductor manufacturing company.
Key Features:
1. Decoder/Demultiplexer Function: The 74HCT138DB118 features 3-to-8 line decoding functionality, which means it can take three address inputs and convert them into eight mutually exclusive outputs. It provides a means to activate one of the eight outputs based on the combination of inputs.
2. High-Speed Operation: This IC operates at high speeds, enabling quick and efficient data processing. It has a propagation delay time of 18 nanoseconds (typical) at 5V supply voltage, allowing for rapid decoding operations.
3. CMOS Technology: The 74HCT138DB118 uses complementary metal-oxide-semiconductor (CMOS) technology, ensuring low power consumption while maintaining high noise immunity. It operates at a wide voltage range, from 2V to 6V, providing flexibility in various applications.
4. Active Low Outputs: The eight outputs of the IC are active-low, which means they are in the logic low state when activated. This feature simplifies circuit design, as additional logic gates or inversion stages might not be required in certain cases
