Charge-Pump Diagram
When in low-power shutdown mode, the MAX205E/MAX206E/MAX211E/MAX213E/MAX241E driver outputsare turned off and draw only leakage currents—even ifthey are back-driven with voltages between 0V and12V. Below -0.5V in shutdown, the transmitter output isdiode-clamped to ground with a 1kΩseriesimpedance.
Shutdown and Enable Control(MAX205E/MAX206E/MAX211E/
MAX213E/MAX241E)
In shutdown mode, the charge pumps are turned off,V+ is pulled down to VCC, V- is pulled to ground, andthe transmitter outputs are disabled. This reducessupply current typically to 1µA (15µA for the MAX213E).The time required to exit shutdown is under 1ms, asshown in Figure 5.
Receivers
All MAX213E receivers, except R4 and R5, are put intoa high-impedance state in shutdown mode (see Tables1a and 1b). The MAX213E’s R4 and R5 receivers stillfunction in shutdown mode. These two awake-in-shutdown receivers can monitor external activity whilemaintaining minimal power consumption.
The enable control is used to put the receiver outputs intoa high-impedance state, to allow wire-OR connection oftwo EIA/TIA-232E ports (or ports of different types) at theUART. It has no effect on the RS-232 drivers or thecharge pumps.
Note: The enable control pin is active low for theMAX211E/MAX241E (EN), but is active high for theMAX213E (EN). The shutdown control pin is active highfor the MAX205E/MAX206E/MAX211E/MAX241E(SHDN), but is active low for the MAX213E (SHDN).
RS-232 Receivers
The receivers convert the RS-232 signals to CMOS-logicoutput levels. The guaranteed 0.8V and 2.4V receiverinput thresholds are significantly tighter than the ±3Vthresholds required by the EIA/TIA-232E specification.This allows the receiver inputs torespond to TTL/CMOS-logic levels, as well as RS-232 levels.
The guaranteed 0.8V input low threshold ensures thatreceivers shorted to ground have a logic 1 output. The5kΩinput resistance to ground ensures that a receiverwith its input left open will also have a logic 1 output. Receiver inputs have approximately 0.5V hysteresis.This provides clean output transitions, even with slowrise/fall-time signals with moderate amounts of noiseand ringing.
In shutdown, the MAX213E’s R4 and R5 receivers haveno hysteresis.

The MAX213E’s receiver propagation delay is typically0.5µs in normal operation. In shutdown mode,propagation delay increases to 4µs for both rising andfalling transitions. The MAX213E’s receiver inputs haveapproximately 0.5V hysteresis, except in shutdown,when receivers R4 and R5 have no hysteresis.
When entering shutdown with receivers active, R4 andR5 are not valid until 80µs after SHDNis driven low.When coming out of shutdown, all receiver outputs areinvalid until the charge pumps reach nominal voltagelevels (less than 2ms when using 0.1µF capacitors).

±15kV ESD Protection
As with all Maxim devices, ESD-protection structuresare incorporated on all pins to protect againstelectrostatic discharges encountered during handlingand assembly. The driver outputs and receiver inputshave extra protection against static electricity. Maxim’sengineers developed state-of-the-art structures toprotect these pins against ESD of ±15kV withoutdamage. The ESD structures withstand high ESD in allstates: normal operation, shutdown, and powereddown. After an ESD event, Maxim’s Eversions keepworking without latchup, whereas competing RS-232products can latch and must be powered down toremove latchup.
ESD protection can be tested in various ways; thetransmitter outputs and receiver inputs of this productfamily are characterized for protection to the followinglimits:
1)±15kV using the Human Body Model
2)±8kV using the contact-discharge method specified
in IEC1000-4-2
3)±15kV using IEC1000-4-2’s air-gap method.ESD Test Conditions
ESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documentstest set-up, test methodology, and test results.
Human Body Model
Figure 6a shows the Human Body Model, and Figure6b shows the current waveform it generates whendischarged into a low impedance. This model consistsof a 100pF capacitor charged to the ESD voltage ofinterest, which is then discharged into the test devicethrough a 1.5kΩresistor.

The IEC1000-4-2 standard covers ESD testing andperformance of finished equipment; it does notspecifically refer to integrated circuits. TheMAX202E/MAX203E–MAX213E, MAX232E/MAX241Ehelp you design equipment that meets level 4 (thehighest level) of IEC1000-4-2, without the need foradditional ESD-protection components.
The major difference between tests done using theHuman Body Model and IEC1000-4-2 is higher peakcurrent in IEC1000-4-2, because series resistance islower in the IEC1000-4-2 model. Hence, the ESDwithstand voltage measured to IEC1000-4-2 isgenerally lower than that measured using the HumanBody Model. Figure 7b shows the current waveform forthe 8kV IEC1000-4-2 level-four ESD contact-dischargetest.

The air-gap test involves approaching the device with acharged probe. The contact-discharge methodconnects the probe to the device before the probe isenergized.
Machine Model
The Machine Model for ESD tests all pins using a200pF storage capacitor and zero dischargeresistance. Its objective is to emulate the stress causedby contact that occurs with handling and assemblyduring manufacturing. Of course, all pins require thisprotection during manufacturing, not just RS-232 inputsand outputs. Therefore,after PC board assembly,theMachine Model is less relevant to I/O ports.
