TRS202 5-V Dual RS-232 Line Driver and Receiver With ±15-kV ESD Protection
1 Features
3 Description
•
The TRS202 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/µs driver output
slew rate.

8 Detailed Description
8.1 Overview
The TRS202 device is a dual driver and receiver that includes a capacitive voltage generator using four
capacitors to supply TIA/EIA-232-F voltage levels from a single 5-V supply. Each receiver converts TIA/EIA-232F inputs to 5-V TTL/CMOS levels. These receivers have shorted and open fail safe. The receiver can accept up
to ±30-V inputs and decode inputs as low as ±3 V. Each driver converts TTL/CMOS input levels into TIA/EIA232-F levels. Outputs are protected against shorts to ground.

8.3 Feature Description
8.3.1 Power
The power block increases and inverts the 5-V supply for the RS-232 driver using a charge pump that requires
four 0.1-µF external capacitors.
8.3.2 RS-232 Driver
Two drivers interface standard logic levels to RS-232 levels. The driver inputs do not have internal pullup
resistors. Do not float the driver inputs.
8.3.3 RS-232 Receiver
Two Schmitt trigger receivers interface RS-232 levels to standard logic levels. Each receiver has an internal 5-kΩ
load to ground. An open input results in a high output on ROUT.
8.4 Device Functional Modes
8.4.1 VCC Powered by 5 V
The device is in normal operation when powered by 5 V.
8.4.2 VCC Unpowered
When TRS202 is unpowered, it can be safely connected to an active remote RS-232 device.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
For proper operation, add capacitors as shown in Figure 12. Pins 9 through 12 connect to UART or general
purpose logic lines. RS-232 lines on pins 7, 8, 13, and 14 connect to a connector or cable.
9.1.1 Capacitor Selection
The capacitor type used for C1–C4 is not critical for proper operation. The TRS202 requires 0.1-µF capacitors,
although capacitors up to 10 µF can be used without harm. Ceramic dielectrics are suggested for the 0.1-µF
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 (for example,
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 µF) to reduce the output impedance at V+ and V–.
Bypass VCC to ground with at least 0.1 µF. 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 charge-pump
capacitors (C1 to C4).
9.1.2 Electrostatic Discharge (ESD) Protection
TI TRS202 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.
9.1.3 ESD Test Conditions
Stringent ESD testing is performed by TI, based on various conditions and procedures. Contact TI for a reliability
report that documents test setup, methodology, and results.
9.1.4 Human-Body Model (HBM)
The HBM of ESD testing is shown in Figure 10. Figure 11 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-kΩ resistor.

Typical Application (continued)
9.2.1 Design Requirements
• VCC minimum is 4.5 V and maximum is 5.5 V.
• Maximum recommended bit rate is 120 kbps.
9.2.2 Detailed Design Procedure
9.2.2.1 Capacitor Selection
The capacitor type used for C1 through C4 is not critical for proper operation. The TRS202 requires 0.1-µF
capacitors. Capacitors up to 10 µF can be used without harm. Ceramic dielectrics are suggested for the 0.1-µF
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 (for example,
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 µF) to reduce the output impedance at V+ and V–.
Bypass VCC to ground with at least 0.1 µF. 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 charge-pump
capacitors (C1 to C4).

10 Power Supply Recommendations
The VCC voltage must be connected to the same power source used for logic device connected to DIN and
ROUT pins. VCC must be between 4.5 V and 5.5 V.
11 Layout
11.1 Layout Guidelines
Keep the external capacitor traces short. This is more important on C1 and C2 nodes that have the fastest rise
and fall times. For best ESD performance, make the impedance from TRS202 ground pin to the ground plane of
the circuit board as low as possible. Use wide metal and multiple vias on both sides of ground pin.

12.4 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
