SN74LVC2G157DCTRG4

Overview

The SN74LVC2G157DCTRG4 is a dual 2-input to 1-line data selector/multiplexer from Texas Instruments, belonging to the LVC logic family. It features a single positive-edge-triggered D-type flip-flop with clear and preset functions for each multiplexer channel. The device operates within a supply voltage range of 1.65V to 3.6V and supports surface-mount installation in an 8-SM package. It is designed for low-voltage applications requiring high-speed data routing with storage capabilities.

Feature Summary

• Integrates two independent 2-to-1 multiplexers with associated D-type flip-flops for data storage
• Supports low-voltage operation suitable for portable and battery-powered systems
• Features positive-edge triggering for synchronized data selection and latching

Applications

• Data routing in low-voltage digital systems
• Signal selection in portable electronic devices
• Memory interface data path management

Procurement Notes

Verify the exact package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the component meets the required operating temperature range and voltage specifications for your specific application environment before integration into production designs.

Selection Notes

Select this component when a compact solution is needed for dual-channel signal switching with integrated storage. Ensure the system voltage aligns with the 1.65V to 3.6V operational range. Consider the 8-SM package size constraints during PCB layout planning to maintain signal integrity and thermal performance.

Part Context
