MAX202
5-V DUAL RS-232 LINE DRIVER/RECEIVER
WITH ± 15-kV ESD PROTECTION
SLLS576E – JULY 2003 – REVISED APRIL 2007
DESCRIPTION/ORDERING INFORMATION
The MAX202 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ± 15-kV ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 5-V supply. The device operates at data signaling rates up to 120 kbit/s and a maximum of 30-V/ µ s driver output slew rate.

APPLICATION INFORMATION
Figure 4. Typical Operating Circuit and Capacitor Values
Capacitor Selection
The capacitor type used for C1–C4 is not critical for proper operation. The MAX202 requires 0.1- µ F capacitors, although capacitors up to 10 µ F can be used without harm. Ceramic dielectrics are suggested for the 0.1- µ F 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., 2 × ) 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 10 µ F) to reduce the output impedance at V+ and V–. Bypass V
charge pumps, decouple V capacitors (C1–C4).
ESD Protection

CC
to ground with a capacitor the same size as (or larger than) the charge-pump
CC
TI MAX202 devices have standard ESD protection structures incorporated on the pins to protect against electrostatic discharges encountered during assembly and handling. In addition, the RS232 bus pins (driver outputs and receiver inputs) of these devices have an extra level of ESD protection. Advanced ESD structures were designed to successfully protect these bus pins against ESD discharge of ± 15-kV when powered down.

ESD Test Conditions
Stringent ESD testing is performed by TI, based on various conditions and procedures. Please contact TI for a reliability report that documents test setup, methodology, and results.
Human-Body Model (HBM)
The HBM of ESD testing is shown in Figure 5 . Figure 6 shows the current waveform that is generated during a discharge into a low impedance. The model consists of a 100-pF capacitor, charged to the ESD voltage of concern, and subsequently discharged into the device under test (DUT) through a 1.5-k resistor.
Figure 5. HBM ESD Test Circuit
Figure 6. Typical HBM Current Waveform
Machine Model (MM)
The MM ESD test applies to all pins using a 200-pF capacitor with no discharge resistance. The purpose of the MM test is to simulate possible ESD conditions that can occur during the handling and assembly processes of manufacturing. In this case, ESD protection is required for all pins, not just RS-232 pins. However, after PC board assembly, the MM test no longer is as pertinent to the RS-232 pins.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
