Note 1: Data in the Typical (“Typ”) column is based on characterization results at +25°C. This data is for design
guidance only and is not tested.
2: The supply current is mainly a function of the operating voltage and frequency. Pin loading, pin rate and
temperature have an impact on the current consumption.
a)The test conditions for all I
DD measurements are:
16XCLK = external square wave, from rail-to-rail; TX = VSS, RXIR = VSS, RESET = VDD.
3: The device disable current is mainly a function of the operating voltage. Temperature also has an impact
on the current consumption. When the device is disabled (RESET = V
SS). The test conditions for all IDD
measurements are:
16XCLK = external square wave, from rail-to-rail; TX = VSS, RXIR = VDD, RESET = VSS; The output pins
are driving a high or low level into infinite impedance.
4: These parameters (shaded) are characterized but are not tested. These values should be used for design
guidance only.
