74LVX157M

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74LVX157M is a low voltage quad 2-input multiplexer housed in a 16-lead SOIC package. It operates within a supply voltage range of 2.0V to 3.6V and supports an input voltage level translation from 5V to 3V. The device features four bits of data selection controlled by common Select and Enable inputs, providing non-inverted outputs. Propagation delay times are specified at 12.5 ns maximum at 2.7V and 7.9 ns maximum at 3.3V. It functions reliably across an operating temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Supports input voltage level translation from 5V to 3V for mixed-voltage system compatibility
• Provides high-speed data selection with guaranteed simultaneous switching noise performance
• Capable of generating any four of sixteen different two-variable logic functions

Signal Switches, Multiplexers, Decoders Applications

• Moving data between two groups of registers to common output buses
• Implementing gating functions as a function generator
• Low power and low noise 3.3V applications

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the LVX157 series includes variants such as M (SOIC), SJ (SOP), and MTC (TSSOP). Ensure the selected part matches the required footprint and pinout for the target design. Confirm RoHS compliance status and check for any product change notices or obsolescence announcements prior to finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad 2-input multiplexer with 5V tolerant inputs is required for 3.3V logic systems. Consider the propagation delay specifications relative to the system clock speed. Evaluate the physical package dimensions against available board space. Verify that the quiescent supply current meets the power budget constraints for the intended application environment.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the LVX logic family, designed for low voltage digital applications. It serves as a standard solution for routing data signals in embedded systems. The component integrates four independent multiplexers into a single integrated circuit, reducing component count compared to discrete solutions. It is widely used in consumer electronics and industrial control interfaces requiring signal switching.
