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. 1 • • • • • ESD Protection for RS-232 Bus Pins: – ±15-kV Human-Body Model (HBM) Meets or Exceeds the Requirements of TIA/EIA-232-F and ITU v.28 Standards Operates at 5-V VCC Supply Operates up to 120 kbit/s External Capacitors: 4 × 0.1 µF Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II 2 Applications • • • • • Device Information(1) Battery-Powered Systems Notebooks Set Top Boxes Palmtop PCs Hand-Held Equipment PART NUMBER PACKAGE BODY SIZE (NOM) TRS202ID SOIC (16) 9.90 mm × 3.91 mm TRS202IPW TSSOP (16) 5.00 mm × 4.40 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.

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. 8.2 Functional Block Diagram 5V DIN POWER 2 TX 2 120 kb/s ROUT 2 RX DOUT RS-232 15 kV HBM 2 RIN RS-232 Copyright © 2016, Texas Instruments Incorporated 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.

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.

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. 11.2 Layout Example Ground C3 1 C1+ VCC 16 VCC PF C1 2 V+ GND 15 3 C1- DOUT1 14 4 C2+ RIN1 13 5 C2- ROUT1 12 Ground C2 Ground 6 V- DIN1 11 7 DOUT2 DIN2 10 C4 8 RIN2 ROUT2 9 Figure 14.
