Product details

The open-drain output allows wired-OR connections and level translation — the output pull-up voltage can be set independently of the supply rail, so a 3.3 V input can drive a 5 V load or vice versa.

Package and footprint — 6-UFDFN (1.45 x 1 mm)

Housed in a 6-pin UFDFN package (6-SON, 1.45 x 1 mm body), this is a tiny surface-mount device. The small footprint saves board space but demands careful soldering — the exposed pad is small, and the leads are not visible after reflow. A hot-air station with fine nozzle and a stencil for the pad are recommended for rework.

Sourcing and supply

For dual-sourcing resilience, the 74LVC1G07 family includes several package options (e.g., SOT-23, SC-70) that share the same logic core — the DCKR variant in SOT-353 is a common alternative if the UFDFN footprint is not required.

Frequently asked questions

Is SN74LVC1G07DRYR open drain or push-pull?

It is an open-drain buffer. The output is an open-drain N-channel MOSFET, not a push-pull stage. This allows wired-OR connections and level shifting — the output high level is set by an external pull-up resistor to any voltage up to 5.5 V, independent of the supply.

Can SN74LVC1G07DRYR be used as a level shifter?

Yes. Because the output is open drain, you can pull it up to a different voltage than VCC. For example, with VCC at 1.8 V and the pull-up resistor connected to 3.3 V, the output swings from 0 V to 3.3 V, translating a 1.8 V logic signal to 3.3 V. The input thresholds are 1.65 V to 5.5 V tolerant, so it works bidirectionally with an external pull-up.

What is the difference between SN74LVC1G07DRYR and SN74LVC1G07DCKR?

The two parts are functionally identical — same buffer, same open-drain output, same supply range and temperature grade. The difference is the package: the DRYR is in a 6-UFDFN (1.45 x 1 mm), while the DCKR is in a 5-pin SOT-353 (SC-70). The DCKR has a larger, easier-to-handle body and is more common in through-hole rework scenarios. Choose the DRYR when board space is critical; choose the DCKR when hand-assembly or probing is frequent.
