74F253SJX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74F253SJX is a dual 4-input multiplexer with 3-STATE outputs, manufactured by Fairchild Semiconductor and distributed by onsemi. It selects two bits of data from four sources using common select inputs (S0, S1). The device features individual Output Enable (OEa, OEb) inputs that force outputs to a high impedance state when HIGH. 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. Propagation delays are specified at 5.0V with 50pF load.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual 4-input multiplexer architecture with non-inverting 3-STATE outputs
• Common select inputs allow simultaneous selection for both sections
• Individual output enable inputs facilitate direct bus-oriented system interfacing

Signal Switches, Multiplexers, Decoders Applications

• Bus oriented systems requiring data selection
• Digital logic implementations acting as 2-pole, 4-position switches
• Data routing in electronic circuits

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging, distinct from standard tube packaging. Confirm the manufacturer origin as Fairchild Semiconductor or onsemi depending on current inventory status. Ensure the SOP package type matches the M16D designation for physical compatibility. Check for RoHS compliance status as indicated in distributor listings.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring dual independent multiplexing with tri-state control. The common select input design simplifies control logic compared to devices with separate select lines. Verify that the 3-STATE output capability meets the bus isolation requirements of the target circuit design. Ensure the operating voltage and temperature ranges align with the system environment.

Signal Switches, Multiplexers, Decoders Part Context

The 74F253 belongs to the 74F series of logic integrated circuits, known for fast switching speeds. This specific part number denotes the Small Outline Package variant with tape and reel packaging. It serves as a functional equivalent to other dual 4-to-1 multiplexers in the industry, providing a compact solution for multi-channel data selection tasks.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include other 74F253 variants from different manufacturers offering identical pinouts and electrical characteristics. Ensure replacement parts maintain the same 3-STATE output functionality and package dimensions for seamless integration into existing designs.
