7.2

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.
