Single-channel noise-immune line driver for mixed-voltage rails
The SN74LVC1G17DRLR is a single non-inverting buffer from the 74LVC low-voltage CMOS family, featuring a Schmitt-trigger input that cleans up slow or noisy edges before the logic threshold. The push-pull output sinks and sources 32 mA, enough to drive a standard LED directly or fan out to several CMOS loads without external buffers.
SOT-553 footprint and layout considerations
Housed in a 5-pin SOT-553 (supplier device package SOT-5), the SN74LVC1G17DRLR occupies roughly 1.6 mm × 1.6 mm of board area — smaller than a single 0805 resistor. The 0.5 mm pitch and 0.3 mm pad width require a fine-pitch soldering profile; standard reflow with a 0.1 mm stencil thickness clears the gap without bridging. The tape-and-reel packaging (7-inch reel, 3000 units per reel per the standard TI carrier) suits high-volume pick-and-place. Cut-tape options are available for prototype or low-volume builds.
Active lifecycle, RoHS3 compliance, and procurement posture
The device is ROHS3 compliant (lead-free, no restricted substances per EU 2015/863), which clears regulatory gatekeeping for EU and California markets without exemption paperwork. Sourced through independent distribution channels with full lot traceability. The base product number 74LVC1G17 covers the entire family; the DRLR suffix denotes the SOT-553 package and reel packaging.
