EURO QUARTZ XO327 OSCILLATOR 32.768kHz Low Power Clock Oscillator FEATURES Micro-miniature 3.2mm x 2.5mm package Exceptionally low supply current <1.5uA at 3.3V supply Wide supply voltage range, 1.5 Volts to 5.5 Volts Tristate function to conserve power Stable and clean CMOS output OUTLINE & DIMENSIONS DESCRIPTION XO327 oscillators are produced in a micro-miniature outline package and provide 32.768kHz with low power consumption, typically 1.5 µA at 3.3 Volts, less for lower supply voltages. Additionally, to conserve power the oscillator has a Tristate function implemented by default. The oscillator can be supplied with any voltage from 1.5 Volts to 5.5 Volts. The XO327 oscillator is an ideal choice for a wide range of battery powered, hand held equipment.
