The SN74LVC1G07DSFR: The open-drain output sinks 32 mA when the input is high and goes high-impedance when the input is low.
The device comes in a 6-pin XFDFN package with a 1x1 mm body. For prototyping or low-volume builds, the part is also available in cut tape (CT) form. Reel quantities are standard for production runs.
Yes. Because the output is open-drain, it can only pull the line low. To get a valid high logic level, you must connect an external pull-up resistor from the output to the desired pull-up voltage (which can be different from the supply voltage). The resistor value depends on the bus capacitance and required rise time; typical values range from 1 kΩ to 10 kΩ.
Within the same 74LVC family, the SN74LVC1G17 is a Schmitt-trigger buffer with push-pull output — it is not open-drain, so it cannot do wired-OR or level translation. The SN74LVC1G07 is the base part number; the DSFR suffix denotes the 6-SON (1x1 mm) package. Other package variants (SOT-23, SC-70) exist under the same base part number but with different suffixes.
