LONG PERIOD TIMER The Fujitsu MB4214 is designed for a long period timer. It contains oscillator, divider (13 stages of flip-flop), output circuit, power supply circuit and parator (2-ch). Arbitrary period is set by external resistor RT, capacitor CT and VS input voltage.
- Time adjustable: 500ms to 100hours
- Oscillator period is controlled by VS input voltage
- Free running oscillation is achieved
- On-chip low power IIL (Integrated Injection Logic) divider
- On-chip zener diode to keep stability
- On-chip two-pair of parators
- Timer output level: TTL level (open...
