TRS232IDW

Drivers, Receivers, Transceivers Overview

The TRS232IDW is a dual RS-232 driver and receiver manufactured by Texas Instruments, designed for operation from a single 5-V power supply. It incorporates an internal capacitive voltage generator to produce TIA/RS-232-F compliant voltage levels using four 1.0-μF charge-pump capacitors. The device supports data rates up to 120 kbit/s and features two drivers and two receivers. It operates within a temperature range of -40°C to 85°C and is housed in a 16-pin SOIC (DW) package. Typical supply current is 8 mA.

Drivers, Receivers, Transceivers Feature Summary

• Complies with TIA/RS-232-F and ITU Recommendation V.28 standards
• Includes integrated capacitive voltage generator for single-supply operation
• Provides ±30-V input tolerance on receiver channels
• Features Schmitt-trigger inputs for noise immunity

Drivers, Receivers, Transceivers Applications

• Battery-powered systems
• Communication terminals
• Modem interfaces
• Computer serial ports

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IDW' corresponds to the industrial temperature grade (-40°C to 85°C) and the wide-body SOIC package format. Confirm RoHS compliance status and lead finish details against the latest Texas Instruments Package Option Addendum prior to ordering.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is required with standard 1.0-μF external capacitors. Ensure the application environment falls within the -40°C to 85°C operating range. Consider the TRS202 if lower capacitance requirements or enhanced ESD protection are necessary.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TRS232 family of dual RS-232 transceivers. It serves as a standard interface solution for converting TTL/CMOS logic levels to RS-232 voltages. The 'I' designation indicates the industrial temperature variant, while 'DW' specifies the 16-pin wide SOIC package type.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS232CDW is the commercial temperature equivalent (0°C to 70°C). For improved ESD performance and smaller capacitor requirements, the TRS202 series is a direct functional upgrade.
