ELECTRICAL CHARACTERISTICS Test conditions

T amb = –40°C to + 85°C, V

CC

= 3.0V to 6.0V. These characteristics are guaranteed by either device characterisation, production

test and or design. They apply within the specified ambient temperature and supply voltage ranges unless otherwise stated using

test circuit Figure 12.
