The 74ACT251 is a high-speed, advanced CMOS octal three-state multiplexer manufactured by Fairchild/ON Semiconductor. It is designed to select one of eight data sources and route it to a single output, providing versatile data selection and routing capabilities in digital systems.

Applications:

• Data selection in computer systems
• Address decoding
• Multiplexing in communication systems
• Routing signals in control systems
• Logic function implementation

Features:

• High-speed operation
• Three-state outputs
• Low power consumption
• Wide operating voltage range
• TTL compatible inputs

Benefits:

• Improved system performance due to high speed
• Flexible data routing capabilities
• Reduced power consumption, extending battery life in portable devices

Additional Details:

The 74ACT251 operates as an 8-to-1 multiplexer with three-state outputs. It features eight data inputs, three select inputs to determine which data input is routed to the output, and an enable input to control the output state. When the enable input is high, the output is disabled and enters a high-impedance state. The device uses advanced CMOS technology to achieve high speed and low power consumption. Refer to the Fairchild/ON Semiconductor datasheet for detailed specifications, including propagation delays, supply voltage range, and operating temperature range.
