Notes: 1. VCC(A) may be as high as 5.5V for overvoltage tolerance but 0.4VCC(A)+0.8V ≤ VCC(B) for the channels to be

enabled and functional normally.

2. For part to function, 0.4VCC(A) must be equal or less than VCC(B) - 0.8V. The voltage on the A port can still

be up to 5.5V without damage to the pins.

3. Pull-up should result in IOL≥150μA.

4. Guaranteed by design and characterization.

5. VIL for port A with envelope noise must be below 0.3VCC(A) for stable performance.

6. When VCC(A) is less than 1V, care is required to make certain that the system ground offset and noise are

minimized such that there is reasonable difference between the VIL present at the UCA9617 A-side input

and the 0.25VCC(A) input threshold.

7. Power supply decoupling capacitors need to be present for both VCC(A) and VCC(B) and the 0.1uF

decoupling for VCC(B) needs to be located near the VCC(B) pin.
