TRS202CDWR

Drivers, Receivers, Transceivers Overview

The TRS202CDWR is a dual RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 5-V supply using an internal charge pump circuit requiring four external 0.1-μF capacitors. The device provides two drivers and two receivers, supporting data signaling rates up to 120 kbit/s with a maximum slew rate of 30 V/μs. It meets TIA/EIA-232-F and ITU v.28 standards. The component includes ±15-kV ESD protection on RS-232 bus pins and latch-up performance exceeding 100 mA per JESD 78 Class II. It is housed in a 16-pin SOIC (DW) package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated dual charge-pump circuit enables operation from a single 5-V power supply without requiring additional voltage rails.
• Built-in electrostatic discharge protection on serial-port connection pins withstands ±15-kV human-body model discharges while powered down.
• Internal design ensures robust latch-up immunity that exceeds 100 mA according to JESD 78 Class II specifications.

Drivers, Receivers, Transceivers Applications

• Battery-powered systems
• Personal digital assistants (PDAs)
• Notebooks and laptops
• Palmtop PCs
• Hand-held equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the latest Package Option Addendum to confirm active status and environmental compliance. Confirm the package drawing matches the required footprint, as the DW designation indicates a wide SOIC variant. Ensure the selected part number aligns with the intended operating temperature range for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing asynchronous communication controllers with standard serial-port connectors under a 5-V logic regime. The device is suitable for designs requiring high ESD tolerance on exposed bus lines. Verify that the PCB layout accommodates the necessary four external capacitors for the charge pump circuit to ensure stable voltage generation.

Drivers, Receivers, Transceivers Part Context

This device belongs to the TRS202 family of 5-V dual RS-232 transceivers. It serves as a direct interface between microcontrollers or UARTs and legacy serial ports. The product is classified as production data and is recommended for new designs within the specified commercial and industrial temperature ranges defined by its suffix.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS202CDWG4 is a lead-free version of this component. Other members of the TRS202 family may offer different pin counts or temperature grades but maintain similar functional interfaces.
