HIN211ECA-T

Overview

The HIN211ECA-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for single +5V power supply operation. It integrates onboard charge pump voltage converters to generate the necessary positive and negative supplies from the 5V input, eliminating the need for external ±12V rails. The device features four drivers and five receivers, supporting data rates up to 230 kb/s. It provides ±15kV ESD protection on transmitter outputs and receiver inputs, ensuring robust performance in harsh environments. The component operates within a temperature range of -40°C to +85°C and includes a low-power shutdown mode to conserve energy in battery-powered applications.

Feature Summary

• Integrates onboard charge pump circuitry to generate internal voltage levels from a single 5V supply
• Provides ±15kV electrostatic discharge (ESD) protection on all RS-232 I/O pins
• Features a low-power shutdown mode to significantly reduce current consumption during idle periods
• Includes hysteresis on receiver inputs to enhance noise rejection capabilities

Applications

• Portable computers and laptop systems requiring high-speed serial communication
• ISDN terminal adaptors and high-speed modem interfaces
• Industrial instrumentation and uninterruptible power supply (UPS) systems
• Peripheral connections such as printers and terminals

Procurement Notes

Verify the specific suffix 'CA' against official Renesas documentation to confirm package type and temperature grade. Ensure the ordering part number matches the exact reel or cut tape configuration required for surface mount assembly processes. Cross-reference the manufacturer date code and lot traceability with the distributor's certificate of analysis to guarantee component authenticity and compliance with RoHS standards.

Selection Notes

Select this component when designing systems that require multiple transmit and receive channels without access to dual polarity power supplies. The HIN211ECA-T is suitable for applications needing high ESD immunity and reduced standby power through its shutdown feature. Compare driver and receiver counts against other family members like the HIN213E if wakeup capabilities are required. Ensure external capacitors meet the minimum capacitance requirements specified in the datasheet for stable charge pump operation.

Part Context

The HIN211ECA-T belongs to the HIN21xE family of RS-232 transceivers, which also includes models like the HIN202E, HIN206E, and HIN213E. This family shares common design characteristics such as single-supply operation and high ESD protection. The 'HIN211' designation specifically indicates a configuration with four drivers and five receivers, distinguishing it from other variants in the series that may offer different channel counts or additional features like active receivers in shutdown mode.

Replacement Considerations

Direct substitutes within the same family include the HIN211EIAZ-T, which offers identical electrical specifications but may differ in packaging or moisture sensitivity level. Verify pin compatibility and functional equivalence before replacing components. Other family members like the HIN213E provide similar core functionality but include two active receivers in shutdown mode, which may not be directly interchangeable if that specific feature is not utilized.
