Applications
The SN74LVC2G157DCTR-P is used in signal routing and data path selection circuits within microcontroller systems, FPGAs, and SoC designs where two analog or digital signal sources must be switched to a single output. It is commonly employed in memory bus switching, I2C/SPI bus sharing, and clock source selection where a single control signal determines which of two inputs is routed to the output. Its wide supply voltage range and low power make it ideal for portable consumer electronics, smartphones, and IoT devices requiring efficient signal multiplexing.

Frequently Asked Questions
What is the function of the SN74LVC2G157DCTR-P?
The SN74LVC2G157DCTR-P is a dual 2-to-1 multiplexer that selects between two input signals per channel and routes the selected input to the output, controlled by a single shared select pin. It contains two independent multiplexer channels, both switching simultaneously when the select input changes.
What supply voltage does the SN74LVC2G157DCTR-P support?
The SN74LVC2G157DCTR-P operates from 1.65V to 5.5V, making it one of the most versatile voltage ranges in the LVC family. This allows direct connection to 1.8V, 2.5V, 3.3V, and 5V logic systems without level translation, simplifying multi-voltage system designs.
What package is the SN74LVC2G157DCTR-P available in?
The SN74LVC2G157DCTR-P comes in a 6-pin SC-70 (SOT-363) surface-mount package, which is one of the smallest IC packages available. Its compact footprint makes it ideal for space-critical applications in wearables, hearing aids, mobile phones, and other miniaturized electronic devices.
Can the SN74LVC2G157DCTR-P be used for I2C or SPI bus multiplexing?
Yes, the SN74LVC2G157DCTR-P can be used for I2C or SPI bus multiplexing by connecting two bus sources to the two inputs of each channel and using the select pin to switch between them. This allows a single microcontroller to share bus peripherals between two subsystems without bus contention, as long as only one source drives the bus at a time.
