Output is CMOS, compatible with most digital logic families at 1.8V supply — the 4 mA typical supply current keeps the thermal budget low in a 4-SMD no-lead package measuring 5.00 mm x 3.20 mm with a 0.90 mm seated height.
No official cross-reference or second-source is published, so a board spin to a current Microchip MEMS oscillator (e.g., the DSC1000 or DSC8000 series) may be required for new designs.
Temperature grade and supply rail — fit check
Supply voltage is 1.8V only — the CMOS output swing is rail-to-rail, so the logic threshold scales with Vdd. A 3.3V oscillator will overdrive the input of a 1.8V-logic device unless a level translator is inserted; the standby (power-down) function pulls the supply current to 1 µA max when disabled.
