TRSF3232IDG4

Drivers, Receivers, Transceivers Overview

The TRSF3232IDG4 is a multichannel RS-232 compatible line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V supply and supports data rates up to 1 Mbit/s with a typical supply current of 300 μA. The device integrates two drivers, two receivers, and a dual charge-pump circuit requiring four external 0.1-μF capacitors. It provides ±15-kV ESD protection on bus pins per the human-body model and exceeds 100 mA latch-up performance per JESD 78 Class II. The ID suffix indicates an industrial temperature range of -40°C to 85°C, packaged in a 16-pin SOIC (D) format.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge-pump circuitry for generating required RS-232 voltage levels from a single low-voltage supply
• Provides robust electrostatic discharge protection exceeding ±15 kV on serial-port connection pins
• Accepts 5-V logic inputs while operating with a 3.3-V supply voltage
• Features high latch-up immunity exceeding 100 mA according to JESD 78 standards

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, thermal grade, and environmental classification. Confirm that the component status remains active for new designs before finalizing procurement plans. Ensure all electrical parameters align with the target application requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing asynchronous communication interfaces requiring full-duplex RS-232 signaling within portable devices. The integrated charge pump eliminates the need for external negative voltage generators. Verify that the system power supply falls within the 3-V to 5.5-V operational range and that the required data rate does not exceed 1 Mbit/s under maximum load conditions.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TRSF3232 family of multichannel RS-232 transceivers. The 'I' designation specifies the industrial temperature range variant (-40°C to 85°C), distinguishing it from the commercial 'C' version. The 'DG4' suffix denotes the SOIC-16 package configuration with lead-free and RoHS-compliant manufacturing processes.
