74F151ASC

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74F151ASC is an 8-input digital multiplexer 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 ambient temperatures from 0°C to +70°C. The device features three select inputs, one active-low enable input, and provides both assertion and negation outputs. Propagation delays vary by path: Select-to-Z ranges from 3.2ns to 9.5ns; Enable-to-Z ranges from 2.5ns to 7.5ns; and Input-to-Z ranges from 1.5ns to 7.5ns under standard test conditions.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides single-pole, eight-position switching capability controlled by three select lines
• Generates any logic function of four variables through proper input manipulation
• Delivers both asserted and inverted data outputs simultaneously

Signal Switches, Multiplexers, Decoders Applications

• Universal function generator for logic circuits
• Data selection from multiple sources
• Control information routing

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the manufacturer origin, as this part was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm that the SOIC package matches the M16A designation. Ensure the operating temperature range meets system requirements, as industrial variants may differ. Check RoHS compliance status separately if required for specific manufacturing standards.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a high-speed 8-channel multiplexer with complementary outputs is required. The SOIC package suits surface-mount assembly processes. Consider the propagation delay specifications relative to system timing constraints. Verify that the power supply voltage remains strictly within the 4.5V to 5.5V range to ensure reliable operation and prevent damage.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74F series of high-speed logic components. It implements a standard 8-to-1 multiplexer architecture compatible with TTL logic levels. The F151A variant specifically offers enhanced speed characteristics compared to earlier generations while maintaining functional compatibility with standard multiplexer applications in digital systems.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74F151APC serves as a pin-compatible alternative in a PDIP package. The 74F151ASJ is available in a wider SOP package. Verify electrical parameters and package dimensions before substitution to ensure mechanical fit and signal integrity compatibility.
