HIN211EIAZ

Overview

The HIN211EIAZ is a full-duplex RS-232 interface transceiver manufactured by Renesas Electronics. It operates on a single +5V supply, utilizing an onboard charge pump to generate the necessary positive and negative voltages for RS-232 signaling without requiring external dual supplies. The device integrates four drivers and five receivers, supporting data rates up to 230 kb/s. It features ±15kV ESD protection on I/O pins, meeting IEC61000 standards. The component includes a low-power shutdown mode with typical current consumption of 1µA. It functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SSOP package.

Feature Summary

• Integrates four drivers and five receivers for complex multi-port serial communication
• Provides ±15kV electrostatic discharge protection on all RS-232 input and output pins
• Features a low-power shutdown mode to conserve energy in battery-operated systems
• Includes onboard charge pump voltage converters eliminating the need for external dual power supplies

Applications

• ISDN terminal adapters and high-speed modem interfaces
• Industrial control systems requiring robust ESD protection
• Battery-powered equipment utilizing low-power shutdown capabilities
• Computer peripheral connections adhering to RS-232E and V.28 specifications

Procurement Notes

Verify the specific suffix 'IAZ' corresponds to the lead-free, RoHS-compliant variant in the SSOP-28 package. Confirm moisture sensitivity level and reflow soldering profile requirements during assembly. Ensure the ordering quantity matches the manufacturer's standard packaging units. Cross-reference the datasheet revision date to confirm compatibility with current design specifications.

Selection Notes

Select this component when a high driver-to-receiver ratio is required for bus topologies. The HIN211EIAZ is suitable for designs needing multiple receive lines driven by fewer transmit lines. Consider the 230 kb/s data rate limit against system baud rate requirements. Evaluate the 28-pin SSOP footprint against available PCB real estate constraints compared to smaller packages.

Part Context

This part belongs to the HIN2xxxE family of RS-232 transceivers from Renesas/Intersil. It shares core architecture with variants like the HIN213EIAZ but differs in the number of integrated drivers and receivers. The family is characterized by single-supply operation and high ESD tolerance, distinguishing it from older dual-supply RS-232 solutions.

Replacement Considerations

The ADM211E is a functional equivalent offering similar driver/receiver counts and performance metrics. Verify pinout compatibility and package dimensions before substitution. Check if the alternative supports the same ±15kV ESD protection level and shutdown current specifications.
