VCC(A) = 0.8 V to 5.5 V[1]; VCC(B) = 2.2 V to 5.5 V; GND = 0 V; Tamb = 40 C to +85 C; unless otherwise specified.
Typical values measured with VCC(A) = 0.95 V and VCC(B) = 2.5 V at 25 C, unless otherwise noted.

[1] VCC(A) may be as high as 5.5 V for overvoltage tolerance but 0.4VCC(A) + 0.8 V VCC(B) for the channels to be enabled and functional
normally.
[2] For part to function, 0.4 VCC(A) must be equal or less than VCC(B) 0.8 V. The voltage on the A port can still be up to 5.5 V without
damage to the pins.
[3] Pull-up should result in IOL 150 A.
[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 1 V, 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 PCA9617A 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 0.1 F decoupling for VCC(B) needs to be
located near the VCC(B) pin.
