Datasheet

Note 2: All voltages are referenced to ground. Current entering the device are specified as positive and currents exiting the device
are negative.
Note 3: Limits are 100% production tested at T
A
= +25°C. Limits over the operating temperature range and relevant supply voltage
range are guaranteed by design and characterization.
Note 4: Currents are specified as individual block currents. Total current for a point in time can be calculated by taking the standby
current and adding any block currents that are active at that time.
Note 5: Receiver sensitivity includes performance degradation contributed by STOP_UP and STOP_DN device pin input offset volt-
age and common mode drift.
