Frequently Asked Questions
What voltage levels does the 74LVC1G240DBVTG4 support?
The 74LVC1G240DBVTG4 operates from 1.65V to 5.5V supply voltage, covering 1.8V, 2.5V, 3.3V, and 5V logic levels. Its 5V-tolerant inputs accept up to 5.5V regardless of VCC setting, enabling direct connection between 3.3V and 5V logic domains without external level shifters.
What applications use the 74LVC1G240DBVTG4 buffer?
This buffer is commonly used for signal conditioning between different voltage domains, UART/SPI level translation, clock distribution buffering, and bus isolation in mixed-voltage designs. Automotive ECUs use it to bridge 3.3V microcontrollers with 5V CAN transceivers and legacy sensor interfaces.
What are equivalent alternatives to the 74LVC1G240DBVTG4?
The SN74LVC1G241DBVR from TI is functionally identical but with active-high enable. The 74LVC1G07DCKR provides open-drain output for wired-OR applications. From NXP, the 74LVC1G240GW offers the same function in an ultra-small XSON6 package at 1.0 × 1.0mm.
