The CD74AC138E is a widely used integrated circuit (IC) component that belongs to the family of high-speed CMOS logic. This IC is a 3-to-8 decoder/demultiplexer with complementary outputs. By decoding the combination of its inputs, it can activate one of the eight outputs based on the input code.
Key features of the CD74AC138E include:
1. High-speed operation: The CD74AC138E is designed with AC performance, allowing it to operate at high speeds. It is capable of handling clock frequencies up to 64 MHz, making it suitable for various applications where synchronous decoding is required.
2. Low power consumption: This IC component consumes low power during operation, making it energy-efficient and suitable for battery-powered devices or systems where power consumption is a concern.
3. Wide operating voltage range: The CD74AC138E has a wide operating voltage range from 2 V to 6 V, providing flexibility and compatibility with different power supply levels.
4. Three binary inputs: It features three input pins (A0, A1, and A2) for selecting the desired output. By setting these inputs to specific binary combinations (0 or 1), the corresponding output will be activated.
5. Eight output pins: The CD74AC138E provides eight output pins (Y0 to Y7) to drive various loads. These outputs are complementary, meaning the active output is driven high while the complementary outputs are driven low
