XD74LS157 – Logic IC Quad 2-to-1 Multiplexer / Data Selector – Xinluda

About this part

The XD74LS157 is Xinluda’s implementation of the industry-standard 74LS157 quadruple 2-line to 1-line data selector/multiplexer. It contains four independent 2-to-1 multiplexers that select a 4-bit word from one of two data sources and route it to four common outputs, controlled by a single common select line. Built on the proven 74LS (low-power Schottky TTL) logic family, the XD74LS157 is a versatile, general-purpose digital building block used widely in data routing, bus multiplexing, and register-transfer applications.

Key Features

• Quadruple 2-line to 1-line data selector/multiplexer (four independent 2-to-1 multiplexers)
• Common Select (A/B) input routes one of two 4-bit data sources to the outputs
• Active-low Strobe/Enable (G) input that disables all four outputs when held high
• Presents true (non-inverted) data at the outputs (74LS157 vs. inverting 74LS158)
• 74LS low-power Schottky TTL logic family
• 5 V nominal TTL supply operation
• 16-pin DIP (DIP-16) through-hole package
• RoHS compliant

Applications

• Data bus multiplexing and signal routing
• Source/operand selection in arithmetic and register-transfer logic
• Parallel-to-serial conversion support and data steering
• Address/data selection in memory and microprocessor systems
• General-purpose digital logic and educational/prototyping boards
