HIN211ECAZ

Overview

The HIN211ECAZ is an RS-232 interface integrated circuit manufactured by Renesas Electronics Corporation, belonging to the HIN211 series. It functions as a full-duplex transceiver with four drivers and five receivers. The device operates on a single +5V power supply (4.5V to 5.5V) with onboard charge pumps generating ±10V supplies using only 0.1µF capacitors. It supports data rates up to 230 kb/s and features ±15kV ESD protection on I/O pins. The component is housed in a 28-pin SSOP package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump voltage converters generate required positive and negative supplies from a single 5V source without external transformers.
• Transmitter outputs and receiver inputs are protected against electrostatic discharge events up to ±15kV.
• Drivers feature true TTL/CMOS input compatibility and slew rate-limited outputs to minimize electromagnetic interference.
• Receivers include hysteresis to significantly improve noise rejection capabilities.

Applications

• High-speed RS-232 communications ports in computer systems
• Portable devices including laptops and mainframes
• Peripheral connections for printers and terminals
• Instrumentation and uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm the exact temperature grade and packaging configuration. Ensure the selected variant matches the required operating environment and RoHS compliance standards before integration into the design.

Selection Notes

Select this component when designing systems requiring multiple transmit and receive channels within a single RS-232 interface. It is suitable for applications where dual voltage supplies are unavailable, leveraging the internal charge pump. Consider the 28-pin SSOP footprint constraints and the 0°C to +70°C commercial temperature range during board layout.

Part Context

The HIN211ECAZ is part of the broader HIN202E, HIN206E, HIN207E, HIN208E, HIN211E, HIN213E, and HIN232E family of RS-232 transmitters and receivers. This family meets EIA high-speed RS-232E and V.28 specifications, offering various driver/receiver combinations to accommodate diverse interface requirements.

Replacement Considerations

HIN211EIAZ-T: Industrial temperature grade (-40°C to +85°C) version of the same functional device.
