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 IDD 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 = VSS). 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.
