Part Number: TCA9617A
Please help with below questions related with TCA9617A VOL of B side. Thanks a lot!
Datasheet shows VOL B side is 0.5V. Is this value related with external pull up resisters? If not, how could it keep always 0.5V?
Another question is TCA4311 is also bi-directional, why it doesn't need static voltage offset?
In reply to Max Robertson:
Thanks for quick response! Then how to calculate IOL? For example, if pull up resister is 3.3kphm, pull up voltage is 3.3V, then what is value of IOL?
In reply to David Zhao:
You can calculate IOL by: (Vpullup-VOL)/Rpullup
For your case, it looks like it will be [3.3V-0.53V(typical)]/3.3k = 0.84mA
