• Wide operating voltage compatibility
• High noise immunity design
• ESD protection capabilities

Applications

• Memory bus buffering
• Clock distribution circuits
• Signal level translation between different voltage domains
• General purpose digital signal buffering

Procurement Notes

Verify the manufacturer designation on the component marking against official Etek Microelectronics documentation. Confirm the specific package type and pinout configuration required for your PCB layout. Ensure that the ordering suffix matches the exact tape and reel or tube specifications needed for your assembly process. Cross-reference the datasheet revision date to ensure compliance with current RoHS and REACH regulations.

Selection Notes

Select this component when a dual-channel non-inverting buffer is required for low-voltage digital applications. Consider the LVC series characteristics for compatibility with modern CMOS logic families. Evaluate the package size constraints against the available footprint options. Verify that the output drive strength meets the load requirements of the connected circuitry without exceeding absolute maximum ratings.

Part Context

This part is part of the broader 74LVC logic family, which is widely used in portable and battery-powered devices due to its low power consumption and wide voltage range. Similar parts from other manufacturers include the SN74LVC2G34 from Texas Instruments and the 74LVC2G34 from Nexperia. These components share functional similarities but may differ in packaging, electrical parameters, and manufacturing processes.

Replacement Considerations

Direct replacements include the SN74LVC2G34DBVR from Texas Instruments and the 74LVC2G34GW from Nexperia. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Check for any differences in propagation delay or output drive strength that might affect circuit timing.
