Oscillator
6V < VS < 18V; all outputs open; Tj = -40°C...130°C, unless otherwise specified.
7.3
Power-on reset (Vs)
All outputs open; Tj = - 40°C...130 °C, unless otherwise specified.
7.4
Voltage regulator V1
The voltages are referred to ground and currents are assumed positive, when the current
flows into the pin. 5.25V < VS < 27V; Tj = -40°C...130°C, unless otherwise specified.
