ELECTRICAL SPECIFICATIONS—MIXED 5 V/3 V OR 3 V/5 V OPERATION
All voltages are relative to their respective ground. 5 V/3 V operation: 4.5 V ≤ V
DD1
≤ 5.5 V, 3.0 V ≤ V
DD2
≤ 3.6 V. 3 V/5 V operation:
3.0 V ≤ V
DD1
≤ 3.6 V, 4.5 V ≤ V
DD2
≤ 5.5 V. All minimum/maximum specifications apply over the entire recommended operation range,
unless otherwise noted. All typical specifications are at T
A
= 25°C, V
DD1
= 3.3 V, V
DD2
= 5 V or V
DD1
= 5 V, V
DD2
= 3.3 V.
