VCC = 1.8 V − 5.5 V
Fast
VCC = 1.8 V − 5.5 V
Fast−Plus
VCC = 2.5 V − 5.5 V
TA = −405C to +855C

14. Test conditions according to “A.C. Test Conditions” table.
15. The New product Rev E is identified by letter “E” or a dedicated marking code on top of the package.
16. Tested initially and after a design or process change that affects this parameter.
17. tPU is the delay between the time VCC is stable and the device is ready to accept commands.
