74F253SC

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74F253SC is a dual 4-input multiplexer with 3-STATE outputs, housed in a 16-Lead Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of 0°C to +70°C. The device features common select inputs (S0, S1) for two independent sections, allowing selection of data from four sources. Propagation delays are specified between 2.5ns and 15.0ns depending on the signal path and operating conditions.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual 4-input multiplexer architecture with non-inverting 3-STATE outputs
• Individual Output Enable inputs allow switching to high impedance state
• Common select inputs control both multiplexer sections simultaneously

Signal Switches, Multiplexers, Decoders Applications

• Bus-oriented systems requiring direct interface capability
• Data routing applications utilizing common select lines
• Logic implementation of 2-pole, 4-position switches

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm the exact package type and reel configuration. Ensure that the selected variant matches the required lead-free compliance standards and environmental certifications. Cross-reference the part number with official distributor catalogs to validate current availability and manufacturing status before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing circuits requiring dual multiplexing functions with bus-compatible outputs. Consider the 3-STATE output capability for managing shared signal lines without external buffering. Evaluate the propagation delay specifications against system timing requirements to ensure signal integrity across the intended operating temperature range.
