DESCRIPTION/ORDERING INFORMATION
The TRS207 consists of five line drivers, three 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 devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/μs driver output
slew rate.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltages are with respect to network GND.
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.

APPLICATION INFORMATION (continued)
Capacitor Selection
The capacitor type used for C1–C4 is not critical for proper operation. The TRS207 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 (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 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–C4).
Electrostatic Discharge (ESD) Protection
TI TRS207 devices have standard ESD protection structures incorporated on the pins to protect against
electrostatic discharges encountered during assembly and handling. In addition, the RS-232 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
ESD testing is stringently 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, while 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 DUT through a 1.5-kΩ resistor.

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 is no longer as pertinent to the RS-232 pins.
