Overview of SN74LV157ADGVR from Texas Instruments

The SN74LV157ADGVR is a high-performance, quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments, designed to operate from a 2-V to 5.5-V VCC supply. This versatile IC is part of the SN74 family and is commonly used in applications such as data routing, signal gating, and multiplexing due to its ability to efficiently select between two sets of four data sources.

Key Features

• Logic Type: 2-Line to 1-Line Data Selector/Multiplexer
• Supply Voltage Range: 2 V to 5.5 V
• Operating Temperature: -40°C to 85°C
• Package: TVSOP-16 (Very Thin Shrink Small Outline Package)
• Output Drive Capability: ±8-mA at 5 V
• Logic Family: LV
• Propagation Delay Time: Fast switching speeds

Functional Description

The SN74LV157ADGVR features four input select lines (A, B, C, and D), two common data select inputs (S0 and S1), four common output enable inputs (OE), and four mutually exclusive outputs (Y). By manipulating the select inputs, users can steer any one of the data inputs to the output, providing a great deal of flexibility in data management. The OE input is active-low and ensures that the outputs are in a high-impedance state when OE is high.

Applications

Thanks to its low power consumption and high-speed operation, the SN74LV157ADGVR is suited for a wide array of applications including:

• Data routing
• Signal gating
• Multiplexing
• Function generation
• Communication systems
• Computers and computer peripherals
