HIN211CBZ

Overview

The HIN211CBZ is a single-supply RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for applications where ±12V power supplies are unavailable. It operates on a single +5V supply and integrates onboard charge pump voltage converters to generate the necessary +10V and -10V internal rails. The device meets EIA RS-232E and V.28 specifications with a data rate of 120 kbit/s. It features four drivers and five receivers in an SSOP-28 package. Key electrical parameters include a maximum operating voltage of 5.5V, minimum of 4.5V, and typical operating current of 5mA. It supports full-duplex communication and includes low-power shutdown functionality.

Feature Summary

• Integrates onboard charge pump voltage converters to generate positive and negative supply rails from a single +5V source
• Provides ±15kV electrostatic discharge (ESD) protection on transmitter outputs and receiver inputs
• Features a low-power shutdown mode to conserve energy in battery-powered applications
• Includes three-state TTL/CMOS compatible receiver outputs with hysteresis for improved noise rejection

Applications

• Portable computers, mainframes, and laptops requiring high-speed RS-232 communications ports
• Peripheral devices such as printers and terminals
• Instrumentation systems and uninterruptible power supplies (UPS)
• Modems and ISDN terminal adaptors

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm package type and temperature range. Ensure compatibility with RoHS standards if required. Confirm moisture sensitivity level and storage conditions prior to assembly. Cross-reference pinouts with the official datasheet to prevent integration errors during PCB design.

Selection Notes

Select this component when a single +5V supply is available but traditional dual-rail RS-232 levels are needed. The HIN211CBZ is suitable for designs prioritizing low external capacitor counts due to its integrated charge pump. Consider the 120 kbit/s data rate limit for application speed requirements. Evaluate the SSOP-28 package constraints against available board space and thermal management needs.

Part Context

The HIN211CBZ belongs to the HIN211 family of RS-232 transceivers originally developed by Intersil and now produced by Renesas. This family shares common architecture with variants like HIN211E and HIN211IA, differing primarily in packaging, temperature ratings, and specific feature sets like shutdown modes. It serves as a direct replacement for legacy RS-232 interface solutions requiring simplified power architectures.

Replacement Considerations

Publicly confirmed substitute part numbers include HIN211E and HIN211IA. Verify that alternative packages or suffixes maintain identical pin configurations and electrical characteristics before substitution.
