NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

Figure 4.
RC oscillator frequency as a function of Rt and Ct at
VCC = 1.2 to 3.6 V; Tamb = 25°C.
Ct curve at Rt = 100 kW; R2 = 200 kW.
Rt curve at Ct = 1 nF; R2 = 2 x Rt.
TIMING COMPONENTS LIMITATIONS
The oscillator frequency is mainly determined by Rt . Ct, provided R2 2Rt and R2 . C2 % Rt . Ct. The function of R2 is to minimize the
influence of the forward voltage across the input protection diodes on the frequency. The stray capacitance C2 should be kept as small as
possible. In consideration of accuracy, Ct must be larger than the inherent stray capacitance. Rt must be larger than the ’ON’ resistance in
series with it, which typically is 280 W at VCC = 1.2 V, 130 W at VCC = 2.0 V and 100 W at VCC 3.0 V. The recommended values for these
components to maintain agreement with the typical oscillation formula are: Ct > 50pF, up to any practical value, 10 kW < Rt < 1 MW. In order to
avoid start-up problems, Rt > 1 kW.
