The disable current is the MEMS oscillator core plus the control logic; the output buffer is off, so the clock line floats high-Z. The 6-SMD no-lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Surface-mount assembly; no special reflow profile beyond what the solder paste requires.
