TRS3223EIPW

Drivers, Receivers, Transceivers Overview

The TRS3223EIPW is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V supply and provides two drivers and two receivers with ±15-kV ESD protection on bus pins. The device meets TIA/EIA-232-F standards and supports data rates up to 500 kbit/s with a maximum slew rate of 30 V/µs. It utilizes four external capacitors for charge pump operation. The component features an auto-powerdown mode that reduces standby current to 1 µA when no valid signal is detected, alongside an INVALID output pin for signal status monitoring.

Drivers, Receivers, Transceivers Feature Summary

• Integrated dual charge-pump circuit enabling operation from a single low-voltage supply without external inductors
• Auto-powerdown functionality that automatically disables drivers upon detecting inactive serial ports to minimize power consumption
• Robust electrostatic discharge protection rated at ±15-kV human-body model and ±8-kV IEC contact discharge on all RS-232 bus lines

Drivers, Receivers, Transceivers Applications

• Battery-powered portable systems requiring extended operational life
• Personal Digital Assistants (PDAs) and handheld equipment
• Notebook and laptop computer serial port interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the latest Package Option Addendum, as the TRS3223EIPW may be listed as obsolete or discontinued in current production lists. Confirm availability through authorized distributors and check for alternative active versions such as the TRS3223EIDWR if the PW package is unavailable. Ensure compliance with RoHS requirements and lead finish specifications relevant to the manufacturing date code.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring dual-channel RS-232 communication within a 3-V to 5.5-V voltage range. It is suitable for applications needing high ESD immunity on serial connections and low standby current via auto-powerdown. Verify that the required data rate does not exceed 500 kbit/s and that the system can accommodate the four external 0.1-µF capacitors necessary for the internal charge pump operation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments TRS3223E family of RS-232 transceivers. The 'I' suffix indicates an industrial temperature range of -40°C to 85°C, while the 'PW' suffix designates the TSSOP-20 surface-mount package. It serves as a standard interface solution for connecting asynchronous controllers to serial connectors in mobile and embedded electronics.

Drivers, Receivers, Transceivers Replacement Considerations

The TRSF3223E is a pin-compatible high-speed alternative offering 1-Mbit/s data rates. For lower channel counts, the TRS3221E provides a single-channel option with similar power management features.
