Hello Team,
following question for better understanding of datasheet values: (everthing referred to datasheet SNVSAT4 - June 2017)
Page 10 - DIGITAL INPUT SIGNALS EN, SCL, SDA, CLKIN
1) is the maximum input value for VIL of 0.4V related to Vin?
2) how is the value of VHYS to interpret?
3) do all input signals have a schmitt-trigger behavior?
DIGITAL OUTPUT SIGNALS nINT, SDA
1) is it possible to calculate the source impedance by using these values? i.e. SDA = 0.4V/20mA = 20 Ohm. This means a pull-up of 4k7 is less than 1mA and causes a output low of 1mA x 20Ohm = 0.04V
DIGITAL OUTPUT SIGNALS PGOOD, GP0, GP2
1) similiar question as before regarding calculation of source impedance
Many Thanks
Josef
