TPT3232E-SO3R

Drivers, Receivers, Transceivers Overview

The TPT3232E-SO3R is a dual transmitter/receiver RS-232 transceiver manufactured by 3PEAK. It operates on a single +3 V to +5.5 V power supply and supports data signaling rates up to 250 kbps. The device integrates two drivers and two receivers, converting TTL/CMOS logic levels to RS-232 voltages and vice versa. It requires four external 0.1 μF capacitors for charge pump operation. ESD protection ratings include ±15 kV (HBM), ±12 kV (IEC61000-4-2 Contact Discharge), and ±15 kV (Air-Gap Discharge) for RS-232 bus pins. The component is housed in an SOP16 package with dimensions of 9.9 mm x 3.9 mm and is characterized for an operating temperature range 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 RoHS compliance and halogen-free status as defined by the manufacturer's green product designation. Ensure the required quantity aligns with the standard tape and reel packaging specifications provided in the official documentation.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring dual-channel RS-232 communication within a 3 V to 5.5 V supply range. Verify that the SOP16 package footprint matches the PCB layout constraints. Ensure external capacitor values meet the minimum requirements specified for the target operating voltage to maintain signal integrity at 250 kbps.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TPT3232E family of 3-V to 5.5-V, 250-kbps RS-232 transceivers produced by 3PEAK. The family includes variants with different package options such as SSOP16 and TSSOP16, all sharing identical electrical characteristics and functional capabilities while differing in physical dimensions and thermal properties.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements must match the dual driver/receiver configuration, 250 kbps speed, and SOP16 package. Functionally similar parts may require design adjustments if they differ significantly in ESD protection levels or external capacitor requirements.

Drivers, Receivers, Transceivers FAQ

What are the ESD protection ratings for the RS-232 bus pins?

The RS-232 bus pins offer ±15 kV protection via the Human Body Model (HBM), ±12 kV protection via IEC61000-4-2 Contact Discharge, and ±15 kV protection via IEC61000-4-2 Air-Gap Discharge.

How many external capacitors are required for operation?

The device typically requires four external capacitors (C1 to C4) for the internal charge pump circuitry. Recommended values depend on the supply voltage, generally ranging from 0.1 μF to 0.2 μF.

What is the maximum data rate supported by this transceiver?

The TPT3232E-SO3R supports data signaling rates up to 250 kbps.
