Supply voltage spans 1.8V to 3.3V, so the same part number works across 1.8V, 2.5V, and 3.3V logic rails without a separate regulator or voltage-divider.
Surface-mount footprint and board fit
Housed in a 4-SMD, no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm max — a standard 5×3.2 mm footprint that matches many quartz XO footprints, easing drop-in replacement. Surface-mount mounting suits automated pick-and-place assembly; the no-lead construction minimises parasitic inductance on the output trace.
