SN74LVC157D Quadruple 2-Line to 1-Line Data Selectors/Multiplexers

The SN74LVC157D from Texas Instruments is a high-performance, quadruple 2-line to 1-line data selector/multiplexer that is designed to operate from 2.7 V to 3.6 V, making it ideal for low-voltage and battery-powered applications. This device features a 3.6-V tolerant input which allows for interface flexibility with mixed-voltage systems. It is part of the LVC family, which is known for its low-voltage operation and low power consumption.

The SN74LVC157D is housed in a SOIC-16 package, providing a compact footprint for space-constrained applications. It is characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions. The device allows for the selection of one of two data sources for each output, controlled by the select inputs (A and B), and each multiplexer has an output enable (OE) input which can be used to disable the output, allowing for easier expansion of data buses with wired-OR logic.

Key features of the SN74LVC157D include its high drive capability, with the ability to drive up to 24 mA at the outputs, and its low power consumption, with a typical ICC of only 10 µA, even when operating at maximum frequencies. This makes it an excellent choice for interfacing with high-speed microprocessors or microcontrollers without imposing a significant power burden on the system.

The device also offers robust ESD protection and latch-up performance, which exceeds 250 mA per JESD 17, ensuring that it can withstand the rigors of real-world handling and operation without suffering damage. The SN74LVC157D's performance and reliability make it a preferred choice for a wide range of applications, including data routing, signal gating, and multiplexing in telecommunications, computing, and industrial electronics.

As a testament to its versatility and performance, the SN74LVC157D is widely used by engineers and designers in various applications where efficient data management and low power consumption are critical. Its ease of integration into existing designs, coupled with Texas Instruments' reputation for quality and support, make this multiplexer a go-to component for both prototyping and mass production.
