A standby (power-down) function on pin 1 drops the supply current to 15 µA max, while the active draw is 6.3 mA max at 24 MHz — the standby current is low enough for battery-backed modules that need to preserve the clock state during sleep.
The 4-SMD, no-lead package (2.50 mm x 2.00 mm footprint, 0.90 mm seated height) is a standard MEMS oscillator land pattern — no unusual board layout or via-in-pad requirements.
