SN74LS157DRG4 Quadruple 2-Line to 1-Line Data Selectors/Multiplexers

The SN74LS157DRG4 from Texas Instruments is a high-performance, quadruple 2-line to 1-line data selector/multiplexer that is designed to facilitate the selection of one of two data sources for each output. This integrated circuit is part of the 74LS family, which is known for its low-power Schottky technology, offering a balanced compromise between speed and power consumption.

Encased in an SOP (Small Outline Package), the SN74LS157DRG4 has a compact form factor that is suitable for space-constrained applications. The device features four individual 2-line to 1-line multiplexers, each with its own select input. The select input determines which of the two data inputs (A or B) is passed through to the output.

Key specifications of the SN74LS157DRG4 include:

• Logic Family: LS
• Logic Type: 2-Line to 1-Line Data Selectors/Multiplexers
• Number of Circuits: 4
• Independent Circuits: 4
• Supply Voltage Range: 4.75V to 5.25V
• Operating Temperature Range: 0°C to 70°C
• Propagation Delay Time: 18ns (Max) at 5V
• Output Current: 8 mA

The device is characterized for operation from 0°C to 70°C, providing reliable performance across a wide range of temperature conditions. Additionally, the SN74LS157DRG4 has a typical power dissipation of 19.5 mW per circuit, making it an energy-efficient choice for many digital applications.

Common applications for the SN74LS157DRG4 include data processing, signal routing, and control systems where multiple data sources need to be selectively routed to a single destination. Its low power consumption and high-speed operation make it particularly well-suited for use in personal computers, servers, networking equipment, and other digital systems that require efficient data management.

With its industry-standard SOP packaging, the SN74LS157DRG4 is compatible with a broad range of printed circuit boards and is easy to integrate into existing designs. Texas Instruments' commitment to quality ensures that this multiplexer is a reliable and durable choice for designers seeking to optimize their digital systems.
