Part Number: TCA9617B
Other Parts Discussed in Thread: TCA9517A, TCA9517

Tool/software:

Could both VCCA and VCCB of TCA9617B and TCA9517B be 3.3V? Which means VCCA equal to VCCB. Thank you.

Hi New2day,

The recommended operating conditions on page 4 / 28 of the TCA9617B datasheet show VCCA(max) = VCCB.

VCCB = 3.3V, means VCCA = 3.3V according to the spec:
