DD2

= 3.3 V. Minimum/maximum specifications apply over the entire recommended

operation range: 3.0 V ≤ V

DD1

≤ 3.6 V, 3.0 V ≤ V

DD2

≤ 3.6 V, and −40°C ≤ T

A

≤ +125°C, unless otherwise noted. Switching specifications

are tested with C

L

= 15 pF and CMOS signal levels, unless otherwise noted. Supply currents are specified with 50% duty cycle signals.
