The SN74LVC157ADRG4 from Texas Instruments is a high-performance, quadruple 2-line to 1-line data selector/multiplexer that operates from a 2.7 V to 3.6 V supply. This integrated circuit is designed to provide a multiplexing function with the capability to select one of two data sources for each output. It is part of the LVC family, which is known for its low-voltage operation and compatibility with mixed-voltage system environments.
Key Features
- Wide Operating Voltage Range: The device is functional across a broad voltage range of 2.7 V to 3.6 V, making it suitable for interfacing with both 3.3 V and 2.5 V logic levels.
- High Speed: Possesses a typical tpd of 3.4 ns at 3.3 V, enabling fast data switching and thus suitable for high-speed applications.
- Low Power Consumption: This component is designed for low power consumption, with a typical ICC of only 10 µA (max).
- Multiple Configuration Options: Features four identical 2-line to 1-line selection/multiplexing units, which can be used independently or configured together for wider data buses or more complex switching schemes.
- High Drive Capability: Offers ±24-mA output drive at 3.3 V, which is adequate for driving multiple loads or for bus-termination resistors.
- IOFF Support: The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
- ESD Protection: Provides robust electrostatic discharge (ESD) protection, ensuring reliability and longevity in challenging environments.
