For a customer the control inputs to the TS3DS10224 are being driven by an IC that only supplies 1.8V as logic high. The TS3DS10224 datasheet recommends 0.75*VCC as the minimum VIH, but their voltage is well below that with VCC = 3.3V (1.8V vs 2.475).
They would like to understand the risks associated with violating the recommendation. Can you advise regarding the potential problems that would occur with regular, prolonged use of 1.8V on SA0, SAI, SBI? (The multiplexer control inputs).
