SAA1114

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) CONNECTION DIAGRAMS OSCILLATOR OUTPUT OSCILLATOR INPUT MOTOR OUTPUT n.c. 7Z76024 OSCILLATOR OUTPUT OSCILLATOR INPUT MOTOR OUTPUT VN TEST ALARM INPUT ALARM OUTPUT -- Note The SAAll14 is internally protected against electrostatic damage. However, to be totally safe, it is desirable to take handling precautions into...
