74LVQ151SCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74LVQ151SCX is a low voltage 8-input digital multiplexer housed in a 16-lead SOIC package. It operates within a supply voltage range of 2.0V to 3.6V and supports an operating temperature from -40°C to +85°C. The device provides both true and complementary outputs, with propagation delays ranging from 8.0ns to 28.0ns depending on the input path and voltage. It features guaranteed simultaneous switching noise levels and incident wave switching performance into 75Ω loads.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering code includes the 'X' suffix to confirm tape and reel packaging availability. Confirm the specific package variant matches the required footprint, as the SC designation corresponds to the JEDEC MS-012 narrow SOIC format. Ensure compatibility with the 2.0V to 3.6V supply range during integration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-channel multiplexer with differential outputs is required for low voltage environments. The LVQ series offers improved dynamic threshold performance compared to standard LV families. Consider the propagation delay specifications relative to the system clock speed and ensure the 16-lead SOIC package fits the board layout constraints.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the LVQ family of low voltage logic devices designed for high-speed applications. The LVQ series specifically addresses simultaneous switching noise issues common in dense digital designs. The 74LVQ151 implements an 8-to-1 multiplexing function, serving as a core building block for data path selection and logic synthesis in mixed-signal or purely digital circuits.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check datasheets for alternative 8-input multiplexers in the LVQ or LVC families. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current before substitution.
