Electrical characteristics

In Table 6, Top = -55 °C to 125°C, VDD1 = 4.5 V to 5.5 V, VDD2 = 2.7 V to 3.6 V, unless

otherwise specified. Each input/output, as applicable, is tested at the specified temperature,

for the specified limits, to the tests specified in TABLE IA from the SMD 5962-98580 DLA

Agency Spec. Non-designated output terminals are high level logic, low level logic or open,

except for all IDD tests, where the output terminals are open. When performing these tests,

the current meter must be placed in the circuit such that all current flows through the meter.
