TRS232EIPWR

Drivers, Receivers, Transceivers Overview

The TRS232EIPWR is a dual RS-232 driver and receiver manufactured by Texas Instruments, housed in a 16-pin TSSOP package. It operates from a single 5V supply (4.5V to 5.5V) with a typical supply current of 8mA. The device supports data rates up to 250kbit/s and includes two drivers and two receivers. It provides ESD protection for RS-232 bus pins, rated at ±15-kV Human-body model (HBM), ±8-kV IEC61000-4-2 contact discharge, and ±15-kV air-gap discharge. The operating temperature range for the 'I' suffix version is -40°C to 85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated capacitive voltage generator enables operation from a single 5V supply using only 1μF charge-pump capacitors.
• Provides robust electrostatic discharge protection on RS-232 bus pins compliant with IEC61000-4-2 standards.
• Converts TTL/CMOS logic levels to TIA/RS-232-F voltage levels and vice versa.

Drivers, Receivers, Transceivers Applications

• TIA/RS-232-F interface connections
• Battery-powered systems
• Terminals and modems
• Computer serial port interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the latest TI Package Option Addendum. The datasheet indicates that the TRS232EIPWR variant may be listed as obsolete or have limited availability compared to active alternatives like the TRS232EIDWR. Confirm current production status directly with Texas Instruments or authorized distributors before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 transceiver is required for 5V-only systems. Ensure the design accommodates the 8mA typical supply current and utilizes four 1μF external capacitors for the charge pump. Verify that the -40°C to 85°C industrial temperature range meets the environmental requirements of the target application.

Drivers, Receivers, Transceivers Part Context

The TRS232E series belongs to Texas Instruments' line of RS-232 interface devices designed for asynchronous communication controllers. The 'PW' suffix specifically denotes the 16-pin Thin Shrink Small Outline Package (TSSOP). This family simplifies hardware design by eliminating the need for dual polarity power supplies typically required for RS-232 applications.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS232EIDWR is an active production alternative within the same family, offering identical electrical specifications but potentially different packaging or availability status. Designers should verify pin compatibility and thermal characteristics if substituting obsolete variants with active ones.
