Analog Clock CMOS IC

OVERVIEW

The CF5741 series are analog clock driver ICs

using 32.768kHz reference frequency of crystal

oscillator. Some versions in accordance with the

combinations of each motor drive and alarm output

characteristics can provide a wide range of applica-

tions for various clock speciﬁcations.
