The SN74LVC2G157YZAR is a high-performance, dual 2-line to 1-line data selector/multiplexer from Texas Instruments, designed to operate from 1.65 V to 5.5 V. This makes it suitable for interfacing with both 3.3 V and 5 V systems. The device can be used in a wide range of applications, including data routing, signal gating, and as a function generator.

Key Features

• Operates from 1.65 V to 5.5 V, accommodating a variety of logic levels and systems.
• Provides high-impedance (Hi-Z) state during power up and power down to prevent unwanted data transmission.
• Includes 2-bit binary decoding to save on control lines.
• Features low power consumption, with a typical quiescent current of only 10 µA, making it ideal for battery-powered applications.
• Compatible with down-voltage translation; the input threshold is 1.2V at VCC = 3.3V, allowing interfacing with lower voltage logic without needing level shifters.

Performance Specifications

The SN74LVC2G157YZAR offers high-speed operation, with typical switching times of 3.4 ns at 5 V, 4.1 ns at 3.3 V, and 7.3 ns at 1.65 V. This ensures rapid data selection and low propagation delay in critical applications.

Applications

Due to its versatile nature, the SN74LVC2G157YZAR is suitable for a variety of applications, including:

• Communication systems
• Data processing
• Signal routing in mixed-voltage environments
• Function selection in programmable logic controllers
