HIN211CBZ-T

Overview

The HIN211CBZ-T is a +5V powered RS-232 transceiver from the HIN211 family, manufactured by Renesas Electronics. It integrates onboard charge pump voltage converters to generate ±10V supplies from a single +5V source, eliminating the need for external dual-voltage rails. The device supports data rates up to 120 kbit/s and meets EIA RS-232E and V.28 specifications. It features four drivers and five receivers with TTL/CMOS input compatibility. Key electrical parameters include a supply voltage range of 4.5V to 5.5V, typical operating current of 5mA, and shutdown current of 1µA. The component provides ±15kV ESD protection on transmitter outputs and receiver inputs.

Feature Summary

• Onboard charge pump voltage converters generate required positive and negative voltages from a single +5V power supply using only 0.1µF or greater external capacitors.
• Transmitter outputs and receiver inputs are protected against electrostatic discharge up to ±15kV, enhancing reliability in sensitive environments.
• Receivers feature 0.5V hysteresis to significantly improve noise rejection capabilities during signal processing.
• Drivers provide true TTL/CMOS input compatibility with slew rate-limited outputs and 300Ω power-off source impedance.

Applications

• Portable computers, mainframes, and laptop systems requiring high-speed RS-232 communication ports
• Peripheral devices such as printers and terminals connected via serial interfaces
• Instrumentation equipment and uninterruptible power supplies (UPS) needing robust serial connectivity

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm package type, temperature grade, and RoHS compliance status. Ensure the ordering part number matches the exact pinout and functional variant required for the design. Cross-reference with authorized distributors to validate authenticity and traceability. Confirm moisture sensitivity level and reflow soldering profile requirements prior to assembly.

Selection Notes

Select this component when designing systems limited to a single +5V power rail, as it eliminates the need for complex dual-voltage generation circuits. The integrated charge pump simplifies board layout by reducing external capacitor count. Consider the 120 kbit/s data rate limit; if higher speeds are required, evaluate alternative models within the family. The low shutdown current makes it suitable for battery-powered applications where energy conservation is critical.

Part Context

The HIN211CBZ-T belongs to the HIN211 series of RS-232 transmitters and receivers originally developed by Intersil and now produced by Renesas Electronics. This series is designed to replace older RS-232 interface solutions that required ±12V supplies. The CBZ suffix typically denotes a specific plastic surface-mount package configuration, such as SSOP-28, intended for industrial and commercial temperature ranges.

Replacement Considerations

Direct replacements within the same family include HIN211E and HIN211IA variants, which offer similar functionality but may differ in ESD protection levels or package options. Verify pin compatibility and electrical specifications before substitution. Other compatible parts in the broader RS-232 portfolio should be evaluated based on specific driver/receiver counts and power consumption requirements.
