ABSTRACT:
A battery select circuit and level translator in a digital watch; the battery select circuit uses the voltage from a single battery to power a digital watch's oscillator and high frequency dividers and uses the voltage from two batteries when the watch user desires the watch's horological information to be displayed on the display devices. Also, when only the voltage of a single battery is required, i.e., to power the digital watch's oscillator and high frequency dividers, the power switch causes the voltage from a first battery to be used during the 12 hour A. M. period and then switches to use the voltage from a second battery during the 12 hour P. M. period; thereby causing both batteries to wear out at the same rate.
The level translator which includes level shifters shifts or extends the voltage from the oscillator and high frequency dividers to a higher voltage level to clock the low frequency watch logic.
