HIN232ECB-T

Overview

The HIN232ECB-T is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Renesas Electronics Corporation. It meets all EIA RS-232E and V.28 specifications, designed for applications lacking ±12V power supplies. The device operates on a single +5V supply (4.5V to 5.5V) with onboard charge pump converters generating ±10V using only 0.1µF external capacitors. It features a data rate of 230kbit/s, ±15kV ESD protection on I/O pins, and low power consumption with typical quiescent current of 5mA. The package is SOIC-16.

Feature Summary

• Integrated onboard voltage doubler and inverter eliminates the need for external ±12V power rails.
• High-speed data transmission capability up to 230kbit/s suitable for ISDN and modem applications.
• Robust electrostatic discharge protection rated at ±15kV on transmitter outputs and receiver inputs.
• Low power shutdown mode significantly reduces current consumption for battery-operated systems.

Applications

• Portable computers, laptops, and mainframes requiring serial communication ports
• ISDN terminal adaptors and high-speed modems
• Printers, terminals, and peripheral instrumentation

Procurement Notes

Verify the specific suffix 'CB' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS compliance requirements if mandated by the target assembly process. Cross-reference the ordering code with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required without external negative voltage generators. It is appropriate for designs needing high noise immunity via receiver hysteresis and robust ESD protection. Consider the 230kbit/s speed limit and ensure it aligns with the system's baud rate requirements.

Part Context

This part belongs to the HIN232E family of RS-232 transceivers from Renesas. The family shares common architecture including the charge pump and ESD protection but varies in driver/receiver counts and shutdown capabilities. The HIN232 variant specifically provides two drivers and two receivers.

Replacement Considerations

Direct functional substitutes within the same family include HIN232ECBNZ or HIN232ECBZ-T. Verify that alternative packages maintain the same pin configuration and thermal characteristics.
