UM3232EEUE

The purpose of the low-power shutdown mode in the UM3221E/UM3222E transceivers is to reduce power consumption in battery-powered portable systems or other low power consumption systems. During shutdown, the supply current falls to less than 1 μA, allowing for power savings. The receivers remain active in shutdown mode, enabling monitoring of external signals.

The ESD rating for the transmitter outputs and receiver inputs of the UM3221E/UM3222E/UM3232E series transceivers is ±15kV for both human body mode and IEC61000-4-2 air discharge methods, and over ±8kV for IEC61000-4-2 contact discharge methods. The logic I/O pins are protected to ±2kV for human body mode.

The UM3221E/UM3222E and UM3232E are pin, package, and functionally compatible with the industry standard MAX242 and MAX232, respectively.
