Part Number: TUSB2046B

How a 3.3V power supply for TUSB2046BI should be practicable by not violating datasheet specification ?

Vccmin = 3.3V

This would request zero negative regulation tolerance.

Please clarify.

Hello Guenter,

For standard operating temperature range TUSB2046B (0 to 70C), Vccmin = 3.0V and Vccmax = 3.6V. For the industrial operating range TUSB2046BI (-40 to 85C), the range is tightened to Vccmin = 3.3V and Vccmax = 3.6V. I would recommend setting your default Vcc for an industrial application to 3.45V
