NOTES: 1. The oscillator frequency is defined by the current flowing through the external resistor R2. The voltage at the INT pin is (VCC/2 – Vbe) and hence the
current flowing through R3 is different if R3 is connected to Vbb or to Gnd because of the voltage drop across resistor R1. This voltage drop causes
the oscillator coefficient for tb2 to be different for the two cases of INT terminated to Gnd or to Vbb. Because of this, the oscillator coefficient is speci–
fied with a specific value of R1 whenever INT is connected to Vbb. If R1 is changed, the coefficient will change. Also, any extra current through the
resistor R1 other than the current used by the device will cause timing deviations in tb2 timings (as in the case where two devices are sharing a
common R1 resistor).
2. The oscillator stability with temperature is dependent on the temperature coefficients of the external components. If the capacitance value of the
external capacitor varies more than 5% over the parametric temperature range, the figures quoted for oscillator variation are not valid.
3. The tb1 duration is given by coefficient 4 x R2 x C2 (tb1 duration = tb1 x 4 x R2 x C2).
4. The tb2 duration is given by coefficient x R3 x C2 (tb2 duration = tb2 x R3 x C2).
