TRS3223ECPW

Drivers, Receivers, Transceivers Overview

The TRS3223ECPW 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 supports data signaling rates up to 500 kbit/s with a maximum slew rate of 30 V/µs. The device integrates two drivers and two receivers, utilizing a dual charge-pump circuit that requires four external capacitors. It provides ±15-kV human-body model ESD protection on RS-232 bus pins. The component features an auto-powerdown function that reduces supply current to 1 µA when the serial port is inactive. It is housed in a 20-pin TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated dual charge-pump circuit enabling operation from a single low-voltage supply
• Auto-powerdown functionality for significant standby current reduction during inactivity
• Robust electrostatic discharge protection on all RS-232 bus pins
• INVALID output pin indicating valid signal presence at receiver inputs

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring low power consumption
• Personal Digital Assistants (PDAs)
• Notebook and laptop computers
• Palmtop PCs
• Hand-held equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. Confirm the current production status as some variants may be obsolete. Ensure the selected part matches the required operating temperature range for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring RS-232 communication with minimal external capacitance. Consider the TRSF3223E if higher data rates up to 1 Mbit/s are necessary. Verify that the system voltage falls within the 3-V to 5.5-V operating range. Check compatibility with 5-V logic inputs if using a 3.3-V supply.

Drivers, Receivers, Transceivers Part Context

The TRS3223E series belongs to Texas Instruments' family of low-power RS-232 transceivers. It shares functional similarities with the MAX3222E but offers distinct packaging options. The device is designed to replace older RS-232 solutions by reducing the number of required external components and lowering overall system power consumption.

Drivers, Receivers, Transceivers Replacement Considerations

TRSF3223E is a high-speed pin-compatible alternative offering 1 Mbit/s data rates. MAX3222E serves as a comparable multichannel RS-232 interface solution.
