Product details

Two open-drain buffers in a tiny SC-70-6

Each of the two elements handles one bit, and the open-drain output can sink up to 32 mA.

Because the output is open drain, the high-level voltage is set by an external pull-up resistor to whatever rail the downstream logic needs. The 32 mA sink current is enough to drive an LED, a small relay coil with a flyback diode, or a wired-OR interrupt line shared by multiple peripherals. No high-level output current is specified — the part only pulls low, so the pull-up resistor value and the downstream input leakage determine the rise time and the static power.

Supply flexibility for mixed-voltage designs

In a mixed-voltage system — say a 3.3 V microcontroller talking to a 5 V peripheral — this buffer can sit on the 3.3 V rail and still accept 5 V inputs because the 74LVC family is 5 V tolerant on inputs. The open-drain output then pulls the line low to ground, and the pull-up resistor connects to the 5 V rail, completing the level translation without a second supply.

Active, ROHS3, and ready to quote

It is ROHS3 compliant, cleared for EU and global markets without exemption paperwork.

Frequently asked questions

Is SN74LVC2G07DCKR RoHS compliant?

Yes, it is ROHS3 compliant, with no exemptions that would restrict its use in EU or global markets.

What is the difference between SN74LVC2G07DCKR and SN74LVC2G07DCTR?

Both parts share the same dual open-drain buffer function and 74LVC family. The difference is the package — the DCKR suffix indicates an SC-70-6 package, while the DCTR suffix is an SOT-223-6. Pin assignments differ between the two packages, so verify the footprint against your board layout before substituting.
