SAAl1l4
II SAAll14Z
4 MHz CLOCK CIRCUITS
The SAA1114 is a C-MOS integrated circuit, particularly suited for crystal controlled clocks powered by a single battery. It contains an oscillator, a 22 -stage frequency divider and a driver for a unipolar stepper motor. With an oscillator frequency of 4, 1943 MHz, the output is a 1 Hz pulse of 31,25 ms duration with a current sinking capability of minimum 6 rnA. The SAA 1114Z is the same circuit, but has. in addition an alarm output signal.
Features • Oscillator frequency: 4 MHz • Output for unipolar stepper motor • Single battery power supply • Current consumption: typo 50!JA • Output signal for alarm (SAAll14Z only)
