CMOS output drives standard logic families directly; the Enable/Disable function allows the output to be tri-stated, pulling the supply current from 35 mA typical down to 22 mA max when the clock is gated off. ## Package and footprint for PCB layout Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this is a standard 5.0 x 3.2 mm oscillator footprint — the same land pattern used by many quartz oscillators, easing a drop-in replacement. No end-of-life notification or successor has been announced.","metaTitle":"DSC1121BI2-080.0000T – Microchip MEMS XO, 80 MHz, CMOS","metaDescription":"Microchip DSC1121BI2-080.0000T MEMS oscillator: 80 MHz, CMOS output, ±25 ppm stability, 2.25V-3.6V supply, -40°C to 85°C, 6-SMD.
