The 74FCT257ATSO is a high-speed Quad 2-Input Multiplexer/Selector from Renesas Electronics America. This device selects four bits of data from two sources under control of a common Select input. The data is routed to four outputs with 3-STATE capability. This makes the 74FCT257ATSO ideal for implementing high-performance memory decoders and data routing applications.

Applications:

• Memory decoding
• Data routing
• Address selection
• Bus-oriented applications
• High-performance computing systems

Features:

• High-speed operation: tpd = 4.5 ns (typ)
• Low power consumption: ICC = 6 mA (typ)
• TTL-compatible inputs and outputs
• 3-STATE outputs drive bus lines directly
• ESD protection exceeds 2000 V
• Available in SOIC package

Benefits:

• Improved system performance due to fast switching speeds.
• Reduced power consumption for energy-efficient designs.
• Easy interface with TTL logic devices.
• Versatile use in bus-oriented systems.
• Enhanced reliability due to ESD protection.
• Compact footprint for space-constrained applications.

Additional Details:

The 74FCT257ATSO operates from a 4.75V to 5.25V power supply and is available in a SOIC (Small Outline Integrated Circuit) package. The operating temperature range is -40°C to +85°C. The device features a propagation delay of typically 4.5 ns, enabling high-speed data selection. The output enable control allows for easy expansion of multiplexing capability. The 3-STATE outputs allow multiple devices to share a common bus. The input and output characteristics are designed to be TTL-compatible, facilitating seamless integration with other TTL logic devices.
