TRS3232CDWG4

Drivers, Receivers, Transceivers Overview

The TRS3232CDWG4 is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V supply and supports data signaling rates up to 250 kbit/s. The device integrates two drivers and two receivers with an internal dual charge-pump circuit requiring four external capacitors. It provides ±15-kV ESD protection on bus pins using the human-body model. The component meets TIA/EIA-232-F and ITU v.28 standards, features Schmitt trigger inputs for noise immunity, and accepts 5-V logic inputs while powered by a 3.3-V supply.

Drivers, Receivers, Transceivers Feature Summary

• Integrated dual charge-pump circuit enables operation from a single low-voltage supply without external inductors
• Provides robust ±15-kV ESD protection on serial-port connection pins including ground
• Features Schmitt trigger inputs on receivers to filter noise and ensure signal integrity
• Accepts 5-V logic input levels even when the device is powered by a 3.3-V supply

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 manufacturer's Package Option Addendum to confirm the exact package type and environmental classification. Confirm that the 'G4' suffix indicates lead-free and RoHS compliance status as defined by the manufacturer's eco-plan definitions. Ensure the active production status is current before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring full-duplex RS-232 communication with high ESD tolerance. It is suitable for portable applications due to its low typical supply current of 300 μA. Verify that the required operating temperature range aligns with the commercial grade specifications. Ensure the design can accommodate the four small external capacitors needed for the charge pump.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TRS3232 family of multichannel RS-232 transceivers. The 'C' designation indicates a commercial temperature range of 0°C to 70°C. The 'DW' suffix specifies the wide SOIC package variant. The 'G4' suffix denotes lead-free packaging compliant with RoHS standards. This series serves as an alternative to higher-speed pin-compatible devices like the TRSF3232.

Drivers, Receivers, Transceivers Replacement Considerations

The TRSF3232 is documented as an alternative high-speed pin-compatible device offering 1 Mbit/s operation. Other variants within the same package family include TRS3232CDW and TRS3232IDWR. Verify electrical compatibility and temperature ranges when substituting.
