Product details

Single-gate open-drain buffer for mixed-voltage buses

The SN74LVC1G07DCK3 is a single-bit, non-inverting buffer from the 74LVC family, with an open-drain output that lets it pull a line low while relying on an external pull-up resistor to define the high-level voltage. The open-drain output sinks 32 mA at the low level — enough to drive a standard logic input or an LED indicator through a series resistor.

SC-70-5 footprint and temperature grade

Housed in a 5-pin SC-70-5 (SOT-353) package, the part occupies about 2.0 mm × 2.1 mm of board area. The 0.65 mm pin pitch is fine enough that a hand-solder rework station with a fine tip handles it, but for volume production a stencil and reflow profile matching the JEDEC MSL-1 moisture sensitivity is the standard approach.

Frequently asked questions

Where can I buy SN74LVC1G07DCK3 and check availability?

Submit an RFQ for a firm lead time and lot traceability.

What is the closest functional second-source to SN74LVC1G07DCK3?

The SN74LVC1G125YZPR is a single-gate non-inverting buffer in the same 74LVC family, but its output is 3-state rather than open-drain. The 1G125 drives the output high actively; the 1G07 relies on an external pull-up. They are not pin-compatible — the 1G125 uses a different package (YZPR) — so a board layout change is required.

What package does SN74LVC1G07DCK3 come in?

It is supplied in a 5-pin SC-70-5 (also designated SOT-353) package. The supplier device package is SC-70-5.
