Product details

Single buffer for level translation and signal clean-up

The buffer delivers 32 mA of source and sink current on each output, enough to drive a modest LED, a relay coil through a transistor, or a long PCB trace without extra line drivers.

Wide temperature range and small footprint

The SC-70-5 package (also known as SOT-353) occupies about 2 mm × 2.1 mm, which saves board space in dense designs. The single-element buffer uses one of the five pins for input, one for output, two for supply and ground, and one is a no-connect — a clean layout for a simple signal path.

Frequently asked questions

Is SN74LVC1G34DCKT equivalent to SN74LVC1G34DBVR?

Both parts share the same base number 74LVC1G34 and the same logic function, supply range, and drive capability. The difference is the package: the DCKT variant comes in SC-70-5, while the DBVR variant uses SOT-23-5. They are not pin-compatible — the footprint differs — so a board designed for one cannot take the other without a layout change.
