CF5732 Series
NIPPON PRECISION CIRCUITS INC.
Analog clock CMOS IC
OVERVIEW
The CF5732 series are analog clock driver ICs using 32kHz 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 applications for various clock specifications. The CF5732 series incorporates 4 types of pace adjustment capacitors, which enables to adjust the pace with bonding options.
FEATURES
- Built-in oscillator circuits(32.678 kHz) On-chip feed back resistors (Rf, Rd) Crystal oscillator capacitors (CD, CG) Additional 4 capacitors for pace adjustment. - Debounce circuit (AI terminal) - Single 1.5 V supply - Available as a die
