The MC74F258ADR2 is a Quad 2-Input Multiplexer with 3-State Outputs from Freescale Semiconductor - NXP. This device selects one of two data sources from each of the four multiplexer channels and routes the selected data to the outputs. The 3-state outputs allow for easy connection to bus-oriented systems.
Applications
- Data selection
- Address multiplexing
- Parallel-to-serial conversion
- Logic function generation
Features
- 3-State Outputs: Allows multiple devices to share a common bus.
- High-Speed Operation: Provides fast data selection and switching speeds.
- Low Power Consumption: Minimizes power dissipation in the system.
- Choice of Two Data Sources: Selects one of two inputs for each channel.
- TTL Compatible: Interfaces directly with TTL logic levels.
Benefits
- Simplified Data Selection: Reduces the complexity of data routing and selection logic.
- Improved System Performance: The high-speed operation minimizes delays, enhancing overall system performance.
- Reduced Component Count: Integrates four multiplexer channels into a single package, reducing the number of components needed.
- Flexible Logic Design: Can be used to implement various logic functions and data routing schemes.
Additional Details
The MC74F258ADR2 operates from a 5V power supply. It comes in a SOIC (Small Outline Integrated Circuit) package. The select input determines which of the two data inputs is routed to the output. When the output enable (OE) input is low, the selected data is present at the output. When OE is high, the output is in a high-impedance state.
The operating temperature range is typically 0°C to +70°C. Proper decoupling capacitors should be used near the power supply pins to minimize noise and ensure stable operation. The device is designed to meet or exceed JEDEC standards.
