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 comparator (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 comparators
• Timer output level: TTL level (open collector)
• Plastic 17-pin ZIP Package (Suffix: -PSZ)
