FUJITSU SEMICONDUCTOR DATA SHEET ASSP w w w MB4214 a TIMER D . S a t e e h U 4 t m o .c DS04-29106-2E 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) ABSOLUTE MAXIMUM RATINGS Rating Power Supply Voltage Zener Current Input Voltage Output Voltage Power Dissipation Operating Temperature Storage Temperature NOTE: w w Symbol VCC IZ .D w VO PD TA t a 18 20 18 S a e h t e U 4 .c m o PLASTIC PACKAGE ZIP-17P-M01 PIN ASSIGNMENT (FRONT VIEW) 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 V02 V01 +IN-B +IN-A -IN-B -IN-A OUT-B OUT-A GND OSC/FR RST VS CT VR RT VZ VCC (See NOTE) (TA=25°C) Value Unit V mA V V mW °C °C VIN -0.3 to 18 (VIN≤VCC) 620 (TA≤85°C) -30 to +85 -55 to +125 TSTG Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded.
