XL74LS157 – Multiplexer / Data Selector – Xinluda

The Xinluda XL74LS157 is a quad 2-line to 1-line data selector/multiplexer in a SOP-16 package, built on a low-power Schottky (LS) TTL process with non-inverting (true-form) outputs.

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.

Key Features

• Quad 2-input (2:1) data selector / multiplexer — selects a 4-bit word from one of two sources
• Non-inverting (true-form) outputs
• Single select input plus common active-low strobe/enable
• Low-power Schottky (LS) TTL process with buffered inputs and outputs
• Recommended supply voltage: 4.75 V to 5.25 V (5 V nominal)
• Operating free-air temperature range: 0°C to 70°C (commercial)
• Input clamp diodes for line-ringing protection
• 16-pin SOP surface-mount package; RoHS compliant

Applications

• Dual data-bus multiplexing and source selection
• Parallel data routing in TTL/microprocessor systems
• Function/operand selection in arithmetic and control logic
• Address and data-path multiplexing on legacy boards
• General-purpose 5V digital signal switching

Why Source XL74LS157 from Pacific Component Xchange
