The XL74LS157 from Xinluda is a quad 2-line to 1-line data selector/multiplexer belonging to the popular 74LS (low-power Schottky TTL) logic family. It selects a 4-bit word from one of two data sources and routes it to four non-inverting (true-form) outputs under control of a single select line, with a common active-low strobe (enable) input. This makes it a reliable building block for data-bus multiplexing, parallel signal routing, and source-selection logic in 5V TTL designs.
Supplied in the surface-mount SOP-16 package, the XL74LS157 is a functional equivalent to the industry-standard 74LS157 / SN74LS157 / DM74LS157, allowing it to serve as a drop-in alternative in legacy and cost-sensitive production runs.
The XL74LS157 is a Xinluda-branded part with limited authorized-distributor availability, making it difficult to source through mainstream channels. Pacific Component Xchange specializes in locating hard-to-find, allocated, and obsolete logic and power-management components. As an independent distributor, we provide authenticity-verified inventory, global shipping, and responsive quoting for low-availability parts like this one.

Whether you are maintaining legacy systems or securing supply for a production build, Pacific Component Xchange can help you source the XL74LS157 with confidence.
The XL74LS157 is a Xinluda-branded quad 2-line to 1-line data selector/multiplexer in a SOP-16 package. It selects a 4-bit word from one of two data sources and routes it to four non-inverting outputs, controlled by a single select line and a common active-low strobe input.
Yes. The XL74LS157 is functionally equivalent to the industry-standard 74LS157 / SN74LS157 / DM74LS157 quad 2-to-1 multiplexer and can generally serve as a drop-in alternative in 5V TTL designs using the 16-pin SOP footprint.
It is supplied in a 16-pin small-outline (SOP-16) surface-mount package and is RoHS compliant.
Per the 74LS157 specification, it operates from a recommended 4.75 V to 5.25 V supply (5 V TTL nominal) over a commercial temperature range of 0u00b0C to 70u00b0C, with input clamp diodes for line-ringing protection.
The XL74LS157 is a Xinluda part with limited authorized-distributor stock, so it is not always available through mainstream channels. Pacific Component Xchange sources hard-to-find logic ICs like this oneu2014submit an RFQ and our team will confirm availability, lead time, and pricing.
It is used for dual data-bus multiplexing, parallel data routing, source/operand selection in control and arithmetic logic, and general-purpose 5V digital signal switching.
