TPT3335-QFZR

Drivers, Receivers, Transceivers Overview

The TPT3335-QFZR is a multi-channel RS-232 transceiver manufactured by 3PEAK, housed in a QFN5x5-32 package. It operates on a single 3.0 V to 5.5 V supply and supports data rates up to 1 Mbps. The device integrates three drivers and five receivers, converting TTL/CMOS inputs to RS-232 levels and vice versa. It features an auto power-down mode that reduces standby current to 1 μA typical when no valid signal is detected. ESD protection meets ±15 kV HBM and ±12 kV IEC61000-4-2 contact standards. The operating temperature range spans from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates three drivers and five receivers for multi-channel serial communication
• Features an auto power-down function to minimize standby current consumption
• Includes an always-active ROUT2B output for ring indicator functionality during power down
• Provides robust ESD protection compliant with IEC61000-4-2 and HBM standards

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low standby current
• Industrial human machine interface (HMI) systems
• Notebook computers and servers
• Printers and peripheral devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix QFZR corresponds to the QFN5x5-32 package variant. Confirm RoHS compliance and halogen-free status as defined by the manufacturer's green product criteria. Ensure the application environment stays within the specified -40°C to +125°C temperature range. Validate external capacitor values against the recommended operating conditions for the chosen supply voltage.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring multiple RS-232 channels in a compact footprint. The QFN5x5-32 package offers thermal advantages over SOP variants. Consider the auto power-down feature for battery-operated applications. Verify that the required number of drivers and receivers matches the three and five channel configuration provided by this specific part number.

Drivers, Receivers, Transceivers Part Context

The TPT3335 series includes variants in SOP28, TSSOP28, SSOP28, and QFN5x5-32 packages. The QFZR suffix specifically denotes the QFN5x5-32 package option. All variants share identical electrical characteristics and functional capabilities, differing only in physical package dimensions and thermal properties.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other TPT3335 package variants such as TPT3335-SO5R, TPT3335-TS6R, or TPT3335-SS6R if pin compatibility allows. Cross-brand replacements must match the 3-to-5 channel configuration and 1 Mbps speed rating.
