The 74HCT138DB,118 is an integrated circuit (IC) component that belongs to the 74HCT family. It is a high-speed CMOS (complementary metal-oxide-semiconductor) decoder/demultiplexer with three-to-eight line decoding capabilities. This IC is commonly used in various digital systems and electronic circuits.
Key features of the 74HCT138DB,118 include:
1. High-Speed Operation: The IC is designed to operate at high speeds, making it suitable for applications that require fast data decoding.
2. Three-to-Eight Line Decoding: The IC is capable of decoding three binary inputs (A0, A1, and A2) into eight mutually exclusive outputs (Y0 to Y7).
3. Active Low Outputs: The outputs of the decoder/demultiplexer are active low, meaning that an output is driven to a low logic level when its corresponding input configuration is detected. This feature is advantageous in many circuits for enhancing compatibility with other components.
4. Low Power Consumption: The HCT (High-Speed CMOS TTL-compatible) technology used in this IC enables low power consumption, making it suitable for battery-powered applications or energy-efficient designs.
5. Wide Operating Voltage Range: The IC can operate within a wide voltage range, typically from 2 to 6 volts, providing flexibility in different digital systems
