Notes

6.Not 100% tested except VIXCLK and ΔVIXCLK. Parameters guaranteed by design and characterizations, not 100% tested in production.

7.This range of SCL and SDA input high voltage enables the CY24272 for use with 3.3V, 2.5V, or 1.8V SMBus voltages.

8.Single-ended operation guaranteed only when 0.8 < (VIH,SE – VTH)/(VTH – VIL,SE) < 1.2.
