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.
