HIN232ECBN-T

Overview

The HIN232ECBN-T is a high-speed RS-232 transceiver from the Renesas HIN232E family, designed for single +5V power supply operation. It meets EIA RS-232E and V.28 specifications with a data rate of 230 kbps. The device features onboard charge pump converters generating ±10V supplies using only 0.1µF external capacitors. It provides ±15kV ESD protection on I/O pins per IEC61000 standards. The package is a 16-pin SOIC-Narrow (CBN) with dimensions of 9.9 x 3.9 mm. Operating temperature range is typically 0°C to +70°C.

Feature Summary

• Integrated ±15kV electrostatic discharge protection on transmitter outputs and receiver inputs
• Onboard voltage doubler and inverter requiring minimal 0.1µF external capacitance
• High-speed data transmission capability up to 230 kbps suitable for ISDN applications
• TTL/CMOS compatible inputs with slew-rate limited outputs and current limiting

Applications

• High-speed RS-232 communication ports in portable computers and laptops
• ISDN terminal adaptors and high-speed modems
• Peripheral connections including printers and terminals
• Instrumentation and UPS systems requiring robust ESD protection

Procurement Notes

Verify the specific suffix 'CBN' corresponds to the SOIC-Narrow 16-pin package configuration. Confirm the operating temperature grade matches system requirements, as industrial variants may carry different suffixes. Ensure RoHS compliance documentation aligns with project regulations. Cross-reference the manufacturer part number against official Renesas databases to confirm active status and availability before finalizing procurement plans.

Selection Notes

Select this component when ±12V supplies are unavailable and single 5V operation is required. Choose the HIN232E variant specifically for its higher 230 kbps data rate compared to standard 120 kbps devices. Verify that the narrow SOIC package fits the PCB footprint constraints. Consider the ESD protection level if the application environment poses significant static discharge risks.

Part Context

The HIN232ECBN-T belongs to the HIN232E family of RS-232 transmitters and receivers. This family redesigns the transmitter circuit to improve data rates and slew rates, making it suitable for ISDN and high-speed modem applications. The 'E' designation indicates enhanced ESD protection capabilities compared to non-E versions in the broader HIN series.

Replacement Considerations

Direct replacements within the same family include HIN232ECBNZ-T. Other pin-compatible options like HIN232ACBNZ exist but lack the ±15kV ESD protection feature. Verify functional equivalence regarding data rate and ESD ratings when substituting.
