74LVQ157SC

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74LVQ157SC is a quad 2-line to 1-line data selector/multiplexer belonging to the LVQ logic family. It features four independent multiplexers, each selecting one of two data inputs based on a common select line. The device operates within a supply voltage range of 2V to 3.6V and supports surface-mount installation in a 14-SOIC package. It is designed for high-speed digital signal routing applications requiring low power consumption and robust performance across industrial temperature ranges.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor's logic products are now managed by onsemi. Confirm that the SN prefix or specific ordering suffix matches the exact SOIC-14 package and RoHS compliance requirements. Ensure the component status is active, as legacy parts may have been discontinued or replaced by newer equivalents in the current portfolio.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad multiplexer with low voltage operation (2V to 3.6V) is required. The LVQ series offers faster propagation delays compared to standard LS logic while maintaining lower power consumption than HC series devices. Consider the 14-SOIC package size for PCB layout constraints and verify that the operating temperature range meets the specific environmental conditions of the target application.
