HIN211ECBZ-T

Overview

The HIN211ECBZ-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics. It 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 dual supplies. The device integrates four drivers and five receivers, supporting full-duplex communication with a data rate of 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 to conserve energy in battery-operated systems. It is housed in a CBZ package variant, typically SSOP-28, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates need for external dual voltage supplies
• High electrostatic discharge protection on all RS-232 lines
• Low power shutdown capability for energy conservation
• TTL/CMOS compatible inputs and outputs

Applications

• Portable computers and laptops requiring serial communication
• Industrial instrumentation with harsh electrical environments
• ISDN terminal adaptors and high-speed modems
• Uninterruptible Power Supply (UPS) control interfaces

Procurement Notes

Verify the specific suffix 'CBZ' against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Ensure the ordering code matches the required tape-and-reel quantity. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturing date code for moisture sensitivity level handling requirements during storage and soldering processes.

Selection Notes

Select this component when a single +5V supply is available but traditional ±12V RS-232 levels are needed. The HIN211E family is suitable for applications requiring multiple receiver inputs, specifically five in this configuration. Consider the shutdown feature if power management is critical. Verify that the 230 kb/s data rate meets the system's baud rate requirements. Ensure the SSOP-28 package fits the PCB layout constraints.

Part Context

The HIN211E belongs to the Intersil/Renesas HIN2xxxE series of RS-232 transceivers designed for 5V operation. This family replaces older devices requiring dual supplies. The HIN211E specifically offers a high driver/receiver count compared to simpler variants like the HIN202E. It shares core architecture with the HIN213E but differs in receiver activation during shutdown modes. The series is widely used in legacy serial port implementations modernized for low-voltage systems.

Replacement Considerations

Direct substitutes include the HIN211EIAZ-T or HIN211EIBZ-T depending on the specific package type (SOIC vs SSOP). The MAX211E from Maxim Integrated is a functional equivalent with similar pinouts and specifications. Verify that any replacement maintains the same ESD protection rating and shutdown current characteristics.
