HIN232IB-T

Overview

The HIN232IB-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics Corporation. It meets EIA RS-232E and V.28 specifications, featuring two drivers and two receivers in a 16-SOIC package. The device operates on a single +5V supply (4.5V to 5.5V) with an onboard charge pump generating ±10V from external 0.1µF capacitors. It supports data rates up to 230kbps and includes ±15kV ESD protection on bus pins. The industrial temperature range spans -40°C to +85°C, with a typical supply current of 5mA.

Feature Summary

• Integrated charge pump voltage converter eliminates the need for dual polarity power supplies
• Robust ±15kV electrostatic discharge protection on transmitter and receiver I/O lines
• High-speed data transmission capability suitable for ISDN and modem applications
• Low power consumption with standard operating current requirements

Applications

• High-speed RS-232 communication ports in computer systems
• ISDN terminal adaptors and high-speed modems
• Peripheral connections including printers and terminals
• Instrumentation and UPS systems requiring reliable serial interfaces

Procurement Notes

Verify the specific suffix 'IB' against official Renesas documentation to confirm pinout compatibility and package dimensions. Ensure the ordering code matches the required tape-and-reel quantity if applicable. Confirm RoHS compliance status through the manufacturer's latest product change notification or datasheet revision history before finalizing procurement.

Selection Notes

Select this component when designing systems that require high-speed RS-232 communication without access to negative voltage rails. The integrated charge pump simplifies board layout by reducing external capacitor count. Verify that the 230kbps data rate aligns with system timing requirements and that the 16-SOIC package fits the available PCB footprint constraints.

Part Context

This part belongs to the HIN232E family of RS-232 transmitters and receivers designed for high-speed applications. The family shares common architecture features such as onboard voltage conversion and ESD protection. Variations within the series typically differ in driver/receiver counts or specific package options, but maintain core electrical performance standards defined by the RS-232E specification.

Replacement Considerations

Direct replacements include other members of the HIN232E family such as HIN232ACBNZ or HIN232IBNZ, provided pin configurations are identical. Cross-brand alternatives must be evaluated for compatible voltage ranges, data rates, and ESD protection levels to ensure functional equivalence.
