TPT3232X-SO3R

Drivers, Receivers, Transceivers Overview

The TPT3232X-SO3R is a dual transmitter/receiver RS-232 transceiver manufactured by 3PEAK. It operates on a single +3 V to +5.5 V supply and supports data rates up to 250 kbps. The device meets TIA/EIA-232-F and ITU V.28 standards, utilizing four external 0.1-μF capacitors for charge pump operation. It features ±17 kV HBM ESD protection and accepts ±28-V receiver inputs. Packaged in SOP16 (9.9 mm x 3.9 mm), it is characterized for operation from –40°C to 125°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix SO3R corresponds to the SOP16 package variant when sourcing. Confirm tape and reel quantities match project requirements, as this variant ships in reels of 2500 units. Ensure environmental compliance status aligns with system specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring standard RS-232 signaling with low external capacitor counts. The SOP16 package suits applications needing larger body dimensions compared to TSSOP or SSOP options. Verify that the 250 kbps maximum data rate satisfies the target communication speed requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TPT3232X family of 3V to 5.5V RS-232 transceivers. The 'SO3R' suffix specifically denotes the SOP16 package type with tape and reel packaging. Other variants in the series include TS3R for TSSOP16 and SS3R for SSOP16 packages.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements within the same family include TPT3232X-TS3R and TPT3232X-SS3R. These share identical electrical characteristics but differ in physical package dimensions. Cross-vendor equivalents may require verification of pinout compatibility and ESD protection levels.
