ELECTRICAL CHARACTERISTICS—MAX3111E (continued)
(VCC = +3.0V to +3.6V, VA = TMIN to TMAX, unless otherwise noted. Typical values are measured for baud rate set to 9600baud at
VCC = +3.3V, TA = +25°C.) (Note 2)
Note 2: All currents into the device are positive; all currents out of the device are negative. All voltages are referred to device
ground unless otherwise noted.
Note 3: ICCSHDN(H) represents a hardware-only shutdown. In hardware shutdown, the UART is in normal operation and the charge
pumps for the RS-232 transmitters are shut down.
Note 4: ICCSHDN(H+S) represents a simultaneous software and hardware shutdown in which the UART and charge pumps are
shut down.
Note 5: Transmitter skew is measured at the transmitter zero cross points.
