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)

tions as detailed in the operational sections of this data sheet. Exposure to
absolute maximum rating conditions for extended periods may affect device
reliability.

This device contains circuitry to protect the inputs against dam-
age due to high static voltages or electric fields. However, it is
advised that normal precautions be taken to avoid application of
any voltage higher than maximum rated voltages to this high
