HIN211EIBZ

Overview

The HIN211EIBZ is a ±15kV ESD-protected, +5V powered RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 230 kb/s. The device integrates four drivers and five receivers in a full-duplex configuration. It utilizes onboard charge pumps to generate ±10 V supplies from the single +5 V input, requiring only 0.1 µF external capacitors. The component functions reliably across an operating temperature range of -40 °C to +85 °C with a typical quiescent current of 20 mA.

Feature Summary

• Integrated low-power shutdown mode for energy conservation in battery-powered applications
• Onboard charge pump voltage converters generating positive and negative supplies from a single 5V source
• High electrostatic discharge protection on transmitter outputs and receiver inputs
• TTL/CMOS compatible inputs with slew-rate-limited outputs to minimize electromagnetic interference

Applications

• Portable computers and laptop systems
• ISDN terminal adaptors and high-speed modems
• Industrial instrumentation and UPS systems
• Peripheral connections such as printers and terminals

Procurement Notes

Verify the specific suffix 'IBZ' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and check moisture sensitivity levels before assembly. Confirm that the ordering code matches the required industrial temperature grade and pinout configuration for the target PCB design.

Selection Notes

Select this component when a single +5V supply is available instead of traditional dual ±12V rails. The HIN211EIBZ is suitable for designs requiring multiple receiver lines (five) alongside standard driver counts. Consider the shutdown feature for power-sensitive portable devices. Verify that the 230 kb/s data rate meets the system's communication speed requirements.

Part Context

This part belongs to the HIN211E family of RS-232 interface circuits designed to meet EIA high-speed RS-232E and V.28 specifications. The family includes variants like HIN206E and HIN213E, sharing common features such as ESD protection and onboard charge pumps. The HIN211E variant specifically provides a balanced mix of drivers and receivers for complex serial communication interfaces.

Replacement Considerations

Direct substitutes include other members of the HIN211E family, such as HIN211EIAZ or HIN211EIPZ, depending on the required package format. Cross-reference with HIN206E or HIN213E if the driver/receiver count differs but other electrical characteristics remain compatible.
