Product details

Single buffer with open-drain output — level-shifting and wired-OR workhorse

The SN74LVC1G07DCKRG4: It accepts a supply from 1.65 V to 5.5 V. The open-drain output can sink up to 32 mA (low) while the high side floats, so you can pull it up to a different voltage rail for level translation or wire multiple outputs together for a wired-OR bus. The SC-70-5 package keeps board area minimal.

The open-drain output sinks 32 mA at low level. Because the high-side is open, you can pull the output to any voltage up to 5.5 V, independent of VCC, which is the key feature for level-shifting.

Frequently asked questions

What is the difference between SN74LVC1G07DCKRG4 and SN74LVC1G125DCKR?

Both are single buffers in SC-70-5 packages, but the SN74LVC1G07DCKRG4 has an open-drain output (high-side floats), while the SN74LVC1G125DCKR has a three-state output with an active-low output enable. The open-drain variant is used for wired-OR buses and level-shifting; the three-state variant is for shared bus lines where the output must be high-impedance.
