HIN211CAZ

Overview

The HIN211CAZ is an RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for high-speed serial communication. It integrates four drivers and five receivers within a single package, supporting full-duplex data transmission at rates up to 230 kb/s. The device operates on a single +5V power supply, utilizing onboard charge pumps to generate the necessary positive and negative voltages for RS-232 signaling without requiring external ±12V sources. It features ±15kV electrostatic discharge (ESD) protection on all RS-232 I/O pins, ensuring robustness in industrial environments. The component is housed in a 28-pin SSOP package and complies with EIA RS-232E and V.28 specifications.

Feature Summary

• Integrates four independent drivers and five independent receivers for complex multi-port serial communication applications.
• Provides ±15kV electrostatic discharge (ESD) protection on transmitter outputs and receiver inputs to enhance system reliability.
• Operates from a single +5V power supply using internal charge pump circuitry to generate required voltage levels.
• Supports high-speed data transmission up to 230 kb/s, suitable for ISDN and modem applications.

Applications

• Industrial control systems requiring multiple RS-232 ports
• High-speed modem interfaces
• ISDN terminal equipment
• Embedded systems with limited power supply options

Procurement Notes

Verify the specific suffix 'CAZ' against the manufacturer's official datasheet to confirm the exact temperature range and packaging configuration. Ensure that the ordering information matches the current Renesas product catalog, as suffixes may indicate variations in RoHS compliance or reel quantities. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select the HIN211CAZ when a design requires four transmit and five receive channels in a compact form factor. This component is appropriate for systems operating exclusively on a 5V supply where generating higher voltages internally is preferred. Consider the 28-pin SSOP package constraints regarding PCB space and thermal management. Verify that the 230 kb/s data rate meets the application's throughput requirements.

Part Context

The HIN211CAZ belongs to the HIN211 family of RS-232 transceivers produced by Renesas Electronics, formerly Intersil. This family is characterized by its ability to operate from a single 5V supply while providing standard RS-232 voltage levels. The HIN211 variant specifically offers a high driver-to-receiver ratio, making it distinct from other members of the series that may offer fewer receivers or different configurations.

Replacement Considerations

Direct replacements include the HIN211EIAZ-T and HIN211ECAZ. These parts share the same functional pinout and electrical characteristics but may differ in temperature grades or packaging formats. Verify compatibility with the existing board layout and ensure that any substitute part meets the required ESD protection and data rate specifications.
