TRS232EIN

Drivers, Receivers, Transceivers Overview

The TRS232EIN is a dual RS-232 driver and receiver manufactured by Texas Instruments, housed in a 16-pin PDIP package. It operates from a single 5V supply with a typical current consumption of 8mA. The device supports data rates up to 250kbit/s and provides ±30V input levels for both drivers and receivers. It features integrated ESD protection rated at ±15kV HBM and ±15kV IEC61000-4-2 air-gap discharge. The component meets TIA/RS-232-F standards and includes a capacitive voltage generator requiring four 1μF external capacitors.

Drivers, Receivers, Transceivers Feature Summary

• Integrated capacitive voltage generator enables operation from a single 5V supply without external negative voltage sources.
• Provides robust ESD protection on RS-232 bus pins compliant with IEC61000-4-2 contact and air-gap discharge standards.
• Accepts ±30V input levels on receiver inputs while converting signals to standard 5V TTL/CMOS logic levels.

Drivers, Receivers, Transceivers Applications

• TIA/RS-232-F communication interfaces
• Battery-powered systems requiring low supply current
• Terminals and modems
• Computer serial port connections

Drivers, Receivers, Transceivers Procurement Notes

Verify the obsolete status of the TRS232EIN before procurement planning. Confirm availability through authorized distributors or check for active replacement parts within the TRS232E family. Ensure design timelines account for potential discontinuation impacts and validate that alternative components meet all electrical specifications required for the target application.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual RS-232 transceiver with high ESD immunity is required for through-hole PCB designs. Verify that the system can accommodate the necessary four 1μF charge-pump capacitors. Ensure the operating temperature range of -40°C to +85°C aligns with environmental conditions. Consider pin compatibility if replacing legacy MAX232 designs.

Drivers, Receivers, Transceivers Part Context

The TRS232EIN belongs to the TRS232E series, which are dual RS-232 drivers and receivers designed for general-purpose serial communication. This specific part number denotes the industrial temperature grade variant packaged in a 16-pin Plastic Dual In-Line (PDIP) format. The series is characterized by its ability to generate internal RS-232 voltage levels from a single 5V source.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include TRS232EIDWR and TRS232EIDW. These alternatives offer surface-mount packaging options while maintaining similar electrical characteristics and functionality within the same product family.
