STMicroelectronics 74ACT280 Parity Generator/Checker

The 74ACT280 from STMicroelectronics is a high-speed CMOS device designed to function as a 9-bit odd/even parity generator/checker. This integrated circuit is part of the 74ACT family, which is known for its advanced high-speed CMOS technology, providing both robust performance and low power consumption.

The 74ACT280 is engineered to enhance system reliability by generating a parity bit for each set of eight bits, which can be used to verify the integrity of data during transmission or storage. The parity bit is a simple error-detecting code that is widely used in digital systems to detect single-bit errors in data bytes.

The device features nine inputs (P0 to P8), which include eight data inputs and one parity input/output. When used as a parity generator, the 74ACT280 calculates the parity for the eight data inputs and provides the resulting odd or even parity output. Conversely, when used as a parity checker, the device compares the parity of the eight data inputs with the ninth parity input and indicates whether the parity is correct or not.

Key features of the 74ACT280 include:

• High-Speed Performance: The device operates at a fast speed, ensuring quick parity generation and checking, which is crucial for high-speed data processing and communication systems.
• Low Power Dissipation: With CMOS technology, the 74ACT280 offers minimal power consumption, making it suitable for battery-powered and energy-efficient applications.
• Wide Operating Voltage Range: The device can operate over a wide voltage range from 4.5V to 5.5V, providing flexibility in different system voltage levels.
• Compatibility: The 74ACT280 is fully compatible with 6TTL outputs, allowing for easy integration into existing digital systems that utilize TTL logic.

Whether used in digital error checking in data storage systems, or in high-speed data communications that require error detection, the 74ACT280 provides a reliable solution for enhancing data integrity. Its small footprint and ease of use make it an excellent choice for a wide range of applications in computing, telecommunications, and industrial electronics.
