ELECTRICAL CHARACTERISTICS
T amb = –40°C to 85 °C, V DD = 5V 10%. The input thresholds and output voltage limits for the logic signal pins are
tested and guaranteed by production test. All other parameters are guaranteed by characterisation and design. They apply within
the specified ambient temperature and supply voltage ranges unless otherwise stated.
