Hello, all
Now I am referring the datasheet of ISO7640FMDW, then would like to ask you some items regarding the description.
1. Input H-level voltage on INA, INB, INC and IND
I could find out RECOMMENDED OPERATING CONDITIONS which is on page 3 of the datasheet, which describes High-level input voltage is VIH min:2V ~ max:Vcc. Meanwhile, on page 2, there is the description "The devices have TTL input thresholds and can operate from 2.7 V, 3.3 V and 5 V supplies. All inputs are 5 V tolerant when supplied from 3.3 V or 2.7 V supplies."
Please let me know the maximum value on input H-level voltage when using Vcc1=3.3V and Vcc2=5.0V. Please let me clarify whether this value should be based on "All inputs are 5 V tolerant" or max:Vcc=3.3V.
2. OUTA, OUTB, OUTC and OUTD value when Vcc1(Input Vcc) is OFF
I could find out Table 1. FUNCTION TABLE on page 2, which describes INPUT Vcc and OUTPUT Vcc. Please let me clarify whether these values are identical with Vcc1 and Vcc2 individually.
Also, please let me clarify whether the output on OUTA, OUTB, OUTC and OUTD are all "L" when Vcc1=OFF, Vcc2=5.0V and ENx=5.0V.
Thank you in advance for your information.
Best regards,
