The CD74ACT238E is a high-speed CMOS Logic 3-to-8 Line Decoder/Demultiplexer integrated circuit, designed and manufactured by Texas Instruments. This device is part of the ACT (Advanced CMOS Technology) family, which offers a balanced blend of speed, power consumption, and robustness. It is particularly suitable for implementing decoding and demultiplexing functions in digital systems.

Key Features:

• High-Speed Operation: The CD74ACT238E is capable of operating at high speeds, making it an ideal choice for high-performance systems.
• Wide Operating Voltage Range: It operates over a wide voltage range from 4.5V to 5.5V, providing flexibility in various application environments.
• Low Power Consumption: This device is designed to consume low power, which is critical for energy-sensitive applications.
• High Noise Immunity: Characteristic of the ACT family, the CD74ACT238E has a high level of noise immunity, ensuring reliable operation even in electrically noisy environments.
• Multiple Package Options: It is available in a standard 16-pin DIP package, making it easy to integrate into a wide range of electronic systems.

Product Applications:

The CD74ACT238E is versatile and can be used in various applications, including:

• Memory decoding or data routing in computer systems
• Control systems for industrial automation
• Address decoding for memory and I/O port mapping
