HIN211ECB

Overview

The HIN211ECB is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Harris Corporation, part of the E-family designed for single +5V power supply applications. It meets all EIA RS-232E and V.28 specifications without requiring ±12V supplies. The device features onboard charge pump voltage converters that generate +10V and -10V rails from the 5V input using only 0.1µF external capacitors. Key electrical parameters include a data rate of 230 kbit/s, ±15kV ESD protection on I/O pins, and a typical operating current of 20 mA. It operates within a temperature range of -40°C to +85°C and includes a low-power shutdown mode.

Feature Summary

• Onboard charge pump generates dual polarity voltages from a single 5V source
• High-speed data transmission capability suitable for ISDN and modems
• Integrated electrostatic discharge protection on transmitters and receivers
• Low power shutdown mode for energy conservation in battery systems

Applications

• Portable computers and laptop serial ports
• Industrial instrumentation and UPS systems
• ISDN terminal adaptors and high-speed modems

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities like Intersil/Renesas, as corporate acquisitions may affect part marking. Confirm the specific suffix 'CB' corresponds to the correct package type and temperature grade against official datasheets. Ensure RoHS compliance status matches the required environmental standards for the target assembly process.

Selection Notes

Select this component when a single 5V supply is available but standard RS-232 voltage levels are required. It is appropriate for designs needing high noise immunity due to integrated ESD protection. Consider the shutdown feature if power management is critical. Verify that the 230 kbit/s speed meets the communication requirements and that the SSOP-28 package fits the PCB layout constraints.

Part Context

This device belongs to the HIN211 family of RS-232 transceivers originally developed by Harris Semiconductor. The family was later acquired by Intersil and subsequently Renesas Electronics. These parts are widely recognized for eliminating the need for external dual-voltage power supplies in legacy serial communication interfaces.

Replacement Considerations

Direct replacements include the HIN211EIAZ-T and HIN211EIBZ-T from Renesas/Intersil. Other compatible variants within the same family such as HIN211CBZ-T may offer similar functionality with minor packaging differences. Always verify pin compatibility and electrical specifications before substitution.
