TPT3232E-TS3R

Drivers, Receivers, Transceivers Overview

The TPT3232E-TS3R is a dual driver/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 a typical threshold of 1.25 V with 0.3 V hysteresis. It features ±15 kV HBM and ±12 kV IEC contact ESD protection. Packaged in TSSOP-16 (5.0 x 4.4 mm), it requires four external capacitors (typically 0.1 μF) for charge pump operation. Operating temperature ranges from -40°C to 125°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix TS3R corresponds to the TSSOP-16 package and tape-and-reel quantity of 3000 units. Confirm RoHS compliance and halogen-free status as defined by the manufacturer's green product criteria. Ensure the required external capacitor values match the specific supply voltage conditions during design validation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is needed within a compact TSSOP-16 footprint. It is appropriate for designs requiring high ESD immunity and operation across a wide industrial temperature range. Verify that the system power supply remains within the 3.0 V to 5.5 V limits to ensure proper charge pump functionality and signal integrity.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TPT3232E family, which includes SOP16 and SSOP16 variants. All versions share identical electrical characteristics and pinouts but differ in physical package dimensions and reel quantities. The TS3R suffix specifically denotes the thin-shrink small-outline package configuration.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include TPT3232E-SO3R and TPT3232E-SS3R. These parts are electrically equivalent but utilize different packages (SOP16 and SSOP16 respectively). PCB layout modifications are required due to differing pin spacing and body dimensions.
