Frequently Asked Questions
What is the acceptable operating voltage range for VCC?
The specified operating voltage window for VCC is between 2.0 to 5.5 V.
How should I calculate average power dissipation?
Use the formula: I = C × V × f + I_CC (opr).
What are the operational temperature limits?
The product is rated for an operating temperature range of -40 to 85°C.
Are there precautions regarding reliability under stress?
Continuous heavy loads or significant temp/current changes can degrade reliability, requiring review against the Toshiba Handbook.
