19-0175; Rev 6; 3/05 ±15kV ESD-Protected, +5V RS-232 Transceivers Next-Generation Device Features The MAX202E–MAX213E, MAX232E/MAX241E line drivers/receivers are designed for RS-232 and V.28 communications in harsh environments. Each transmitter output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. The various combinations of features are outlined in the Selector Guide. The drivers and receivers for all ten devices meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 120kbps, when loaded in accordance with the EIA/TIA-232E specification. The MAX211E/MAX213E/MAX241E are available in 28pin SO packages, as well as a 28-pin SSOP that uses 60% less board space. The MAX202E/MAX232E come in 16-pin TSSOP, narrow SO, wide SO, and DIP packages. The MAX203E comes in a 20-pin DIP/SO package, and needs no external charge-pump capacitors. The MAX205E comes in a 24-pin wide DIP package, and also eliminates external charge-pump capacitors. The MAX206E/MAX207E/MAX208E come in 24-pin SO, SSOP, and narrow DIP packages. The MAX232E/MAX241E operate with four 1µF capacitors, while the MAX202E/MAX206E/MAX207E/MAX208E/ MAX211E/MAX213E operate with four 0.1µF capacitors, further reducing cost and board space. ♦ For Low-Voltage Applications MAX3222E/MAX3232E/MAX3237E/MAX3241E/ MAX3246E: ±15kV ESD-Protected Down to 10nA, +3.0V to +5.5V, Up to 1Mbps, True RS-232 Transceivers (MAX3246E Available in a UCSP™ Package) ♦ For Low-Power Applications MAX3221/MAX3223/MAX3243: 1µA Supply Current, True +3V to +5.5V RS-232 Transceivers with Auto-Shutdown™ ♦ For Space-Constrained Applications MAX3233E/MAX3235E: ±15kV ESD-Protected, 1µA, 250kbps, +3.0V/+5.5V, Dual RS-232 Transceivers with Internal Capacitors ♦ For Low-Voltage or Data Cable Applications MAX3380E/MAX3381E: +2.35V to +5.5V, 1µA, 2Tx/2Rx RS-232 Transceivers with ±15kV ESDProtected I/O and Logic Pins Ordering Information PART ________________________Applications Notebook, Subnotebook, and Palmtop Computers Battery-Powered Equipment Hand-Held Equipment TEMP RANGE PIN-PACKAGE MAX202ECPE 0°C to +70°C 16 Plastic DIP MAX202ECSE 0°C to +70°C 16 Narrow SO Ordering Information continued at end of data sheet.

Transition Slew-Rate Circuit _______________Detailed Description The MAX202E–MAX213E, MAX232E/MAX241E consist of three sections: charge-pump voltage converters, drivers (transmitters), and receivers. These E versions provide extra protection against ESD. They survive ±15kV discharges to the RS-232 inputs and outputs, tested using the Human Body Model. When tested according to IEC1000-4-2, they survive ±8kV contactdischarges and ±15kV air-gap discharges. The rugged E versions are intended for use in harsh environments or applications where the RS-232 connection is frequently changed (such as notebook computers). The standard (non-“E”) MAX202, MAX203, MAX205– MAX208, MAX211, MAX213, MAX232, and MAX241 are recommended for applications where cost is critical. +5V to ±10V Dual Charge-Pump Voltage Converter The +5V to ±10V conversion is performed by dual charge-pump voltage converters (Figure 4). The first charge-pump converter uses capacitor C1 to double the +5V into +10V, storing the +10V on the output filter capacitor, C3. The second uses C2 to invert the +10V into -10V, storing the -10V on the V- output filter capacitor, C4. In shutdown mode, V+ is internally connected to VCC by a 1kΩ pull-down resistor, and V- is internally connected to ground by a 1kΩ pull up resistor. RS-232 Drivers With VCC = 5V, the typical driver output voltage swing is ±8V when loaded with a nominal 5kΩ RS-232 receiver. The output swing is guaranteed to meet EIA/TIA-232E and V.28 specifications that call for ±5V minimum output levels under worst-case conditions. These include a 3kΩ load, minimum V CC , and maximum operating temperature. The open-circuit output voltage swings from (V+ - 0.6V) to V-. Input thresholds are CMOS/TTL compatible. The unused drivers’ inputs on the MAX205E–MAX208E, MAX211E, MAX213E, and MAX241E can be left unconnected because 400kΩ pull up resistors to VCC are included on-chip. Since all drivers invert, the pull up resistors force the unused drivers’ outputs low. The MAX202E, MAX203E, and MAX232E do not have pull up resistors on the transmitter inputs. _______________________________________________________________________________________ 9 MAX202E–MAX213E, MAX232E/MAX241E +5V MAX202E–MAX213E, MAX232E/MAX241E ±15kV ESD-Protected, +5V RS-232 Transceivers V+ S1 S2 C1+ VCC C1 S3 S5 C3 IL + S4 GND C1- C2+ S6 C2 RL + C4 S7 VCC GND IL- S8 VC2- PART fCLK RL- MAX202E MAX203E MAX205E–208E MAX211E/213E MAX232E MAX241E fCLK (kHz) 230 230 200 200 140 30 Figure 4. Charge-Pump Diagram When in low-power shutdown mode, the MAX205E/ MAX206E/MAX211E/MAX213E/MAX241E driver outputs are turned off and draw only leakage currents—even if they are back-driven with voltages between 0V and 12V. Below -0.5V in shutdown, the transmitter output is diode-clamped to ground with a 1kΩ series impedance. RS-232 Receivers The receivers convert the RS-232 signals to CMOS-logic output levels. The guaranteed 0.8V and 2.4V receiver input thresholds are significantly tighter than the ±3V thresholds required by the EIA/TIA-232E specification. This allows the receiver inputs to respond to TTL/CMOSlogic levels, as well as RS-232 levels. The guaranteed 0.8V input low threshold ensures that receivers shorted to ground have a logic 1 output. The 5kΩ input resistance to ground ensures that a receiver with 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 slow rise/fall-time signals with moderate amounts of noise and ringing. In shutdown, the MAX213E’s R4 and R5 receivers have no hysteresis. 10 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, and the transmitter outputs are disabled. This reduces supply current typically to 1µA (15µA for the MAX213E). The time required to exit shutdown is under 1ms, as shown in Figure 5. Receivers All MAX213E receivers, except R4 and R5, are put into a high-impedance state in shutdown mode (see Tables 1a and 1b). The MAX213E’s R4 and R5 receivers still function in shutdown mode. These two awake-inshutdown receivers can monitor external activity while maintaining minimal power consumption. The enable control is used to put the receiver outputs into a high-impedance state, to allow wire-OR connection of two EIA/TIA-232E ports (or ports of different types) at the UART. It has no effect on the RS-232 drivers or the charge pumps. Note: The enable control pin is active low for the MAX211E/MAX241E (EN), but is active high for the MAX213E (EN). The shutdown control pin is active high for the MAX205E/MAX206E/MAX211E/MAX241E (SHDN), but is active low for the MAX213E (SHDN). ______________________________________________________________________________________ ±15kV ESD-Protected, +5V RS-232 Transceivers ±15kV ESD Protection As with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The driver outputs and receiver inputs have extra protection against static electricity. Maxim’s engineers developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, shutdown, and powered down. After an ESD event, Maxim’s E versions keep working without latchup, whereas competing RS-232 products can latch and must be powered down to remove latchup. ESD protection can be tested in various ways; the transmitter outputs and receiver inputs of this product family are characterized for protection to the following limits: 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 documents test set-up, test methodology, and test results. Human Body Model Figure 6a shows the Human Body Model, and Figure 6b shows the current waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the test device through a 1.5kΩ resistor.

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

IEC1000-4-2 ESD Test Model t r = 0.7ns to 1ns t 30ns 60ns IEC1000-4-2 The IEC1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifically refer to integrated circuits. The MAX202E/MAX203E–MAX213E, MAX232E/MAX241E help you design equipment that meets level 4 (the highest level) of IEC1000-4-2, without the need for additional ESD-protection components. The major difference between tests done using the Human Body Model and IEC1000-4-2 is higher peak current in IEC1000-4-2, because series resistance is lower in the IEC1000-4-2 model. Hence, the ESD withstand voltage measured to IEC1000-4-2 is generally lower than that measured using the Human Body Model. Figure 7b shows the current waveform for the 8kV IEC1000-4-2 level-four ESD contact-discharge test. 12 Figure 7b. IEC1000-4-2 ESD Generator Current Waveform The air-gap test involves approaching the device with a charged probe. The contact-discharge method connects the probe to the device before the probe is energized. Machine Model The Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resistance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. Of course, all pins require this protection during manufacturing, not just RS-232 inputs and outputs. Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports. ______________________________________________________________________________________ ±15kV ESD-Protected, +5V RS-232 Transceivers Capacitor Selection The capacitor type used for C1–C4 is not critical for proper operation. The MAX202E, MAX206–MAX208E, MAX211E, and MAX213E require 0.1µF capacitors, and the MAX232E and MAX241E require 1µF capacitors, although in all cases capacitors up to 10µF can be used without harm. Ceramic, aluminumelectrolytic, or tantalum capacitors are suggested for the 1µF capacitors, and ceramic dielectrics are suggested for the 0.1µF capacitors. When using the minimum recommended capacitor values, make sure the capacitance value does not degrade excessively as the operating temperature varies. If in doubt, use capacitors with a larger (e.g., 2x) nominal value. The capacitors’ effective series resistance (ESR), which usually rises at low temperatures, influences the amount of ripple on V+ and V-. Use larger capacitors (up to 10µF) to reduce the output impedance at V+ and V-. This can be useful when “stealing” power from V+ or from V-. The MAX203E and MAX205E have internal charge-pump capacitors. Bypass V CC to ground with at least 0.1µF. In applications sensitive to power-supply noise generated by the charge pumps, decouple VCC to ground with a capacitor the same size as (or larger than) the chargepump capacitors (C1–C4). V+ and V- as Power Supplies A small amount of power can be drawn from V+ and V-, although this will reduce both driver output swing and noise margins. Increasing the value of the charge-pump capacitors (up to 10µF) helps maintain performance when power is drawn from V+ or V-. Driving Multiple Receivers Each transmitter is designed to drive a single receiver. Transmitters can be paralleled to drive multiple receivers. Driver Outputs when Exiting Shutdown The driver outputs display no ringing or undesirable transients as they come out of shutdown. High Data Rates These transceivers maintain the RS-232 ±5.0V minimum driver output voltages at data rates of over 120kbps. For data rates above 120kbps, refer to the Transmitter Output Voltage vs. Load Capacitance graphs in the Typical Operating Characteristics. Communication at these high rates is easier if the capacitive loads on the transmitters are small; i.e., short cables are best. Table 2.
