operate as specified. If the device is used under operating conditions other than the operating conditions (supply
voltage, operating temperature range, specified AC/DC values etc.), malfunction may occur. Thus, when designing
products which include this device, ensure that the operating conditions for the device are always adhered to.
The operating conditions for a device are operating conditions under which it can be guaranteed that the device will
