LOW POWER CONSUMPTION OSCILLATORS LPO 8 SERIES, Model 7 8 pin Dual-in-Line Package OUTLINES AND DIMENSIONS DESCRIPTION The Euroquartz LPO14 series of low power consumption oscillators are ideal parts providing the time base signals for real-time clocks. The oscillators have very low current consumption (as low as 14mA) and are ideal for battery operated devices such as data logging and portable test equipment. FEATURES · · · · · Very low current consumption from 14mA Industry-standard 8 pin DIL package Wide frequency range, from 1Hz to 160kHz Supply Voltage from 2.0 Volts to 15.0 Volts Standard CMOS output SPECIFICATION Input Voltage: Frequency Range: +3.3 VDC +5.0VDC +2.0 Volts to +7.0 Volts is available 20kHz to 160kHz (Limited to standard frequencies.)
