The MB4214 contains reference voltage circuit, oscillator, divider and comparator as shown in Fig. 1. Oscillator frequency is arbitrary controlled by external resistor RT, capacitor CT and VS input voltage.
MB4214 consists of 13 stages of divider circuit which is constructed by IIL (Intergrated Injection Logic) technique. It expands the oscillator period up to 4096times. About 100hours period is achieved by a small capacitor.
MB4214 (Long period low frequency) is achieved when OSC/FR pin is connected to GND.
