HIN208ECB-T

Overview

The HIN208ECB-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates on a single +5V power supply and includes onboard charge pump voltage converters to generate the required positive and negative voltages for RS-232 signaling, eliminating the need for external ±12V supplies. The device features two drivers and two receivers, supporting full-duplex communication with a data rate of up to 230 kbps. It provides robust protection against electrostatic discharge (ESD) on both transmitter outputs and receiver inputs, rated at ±15kV according to IEC61000 standards. The component meets all EIA high-speed RS-232E and V.28 specifications.

Feature Summary

• Onboard charge pump voltage converters generate necessary supply rails from a single +5V source
• High-speed operation compatible with ISDN and modem applications
• Integrated ±15kV ESD protection on RS-232 I/O pins
• Low power shutdown mode for energy conservation in battery-powered systems

Applications

• Portable computers and laptops requiring serial communication ports
• ISDN terminal adaptors and high-speed modems
• Industrial instrumentation and UPS systems
• Printers and terminals connected via RS-232 interfaces

Procurement Notes

Verify the specific suffix 'CB' indicates the narrow SOIC package configuration when sourcing. Confirm RoHS compliance status as some variants may differ. Check for obsolescence notices or lifecycle changes directly from Renesas documentation before finalizing procurement plans.

Selection Notes

Select this component for designs requiring dual driver/receiver channels in a compact surface-mount format. Ensure the application environment does not exceed the specified operating temperature range. Verify that the system's power supply remains stable within the 4.5V to 5.5V window to maintain signal integrity.

Part Context

This part belongs to the HIN202E/HIN206E/HIN207E/HIN208E/HIN211E/HIN213E/HIN232E family of RS-232 interface circuits. These devices are designed to replace older transceivers that required complex multi-voltage power supplies, simplifying board layout and reducing component count in modern low-voltage digital systems.

Replacement Considerations

Direct pin-compatible alternatives within the same family include HIN202E, HIN206E, HIN207E, HIN211E, HIN213E, and HIN232E series components. Verify functional equivalence regarding driver/receiver counts and shutdown capabilities before substitution.
