HIN232EIBN-T

Overview

The HIN232EIBN-T is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Renesas Electronics. It meets EIA RS-232E and V.28 specifications, designed for systems lacking ±12V supplies. The device operates on a single +5V power supply with onboard charge pumps 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 a typical supply current of 5mA. The package is SOIC-16.

Feature Summary

• High-speed data transmission capability up to 230kbit/s suitable for ISDN and modem applications
• Integrated onboard voltage doubler and inverter requiring minimal external capacitance
• Robust electrostatic discharge protection on all RS-232 input and output pins
• Low power shutdown mode functionality for energy conservation in battery-powered devices

Applications

• Computer portable, mainframe, and laptop systems
• Peripheral connections including printers and terminals
• Instrumentation and uninterruptible power supply (UPS) units
• Modems and ISDN terminal adaptors

Procurement Notes

Verify the specific suffix 'IBN-T' against official Renesas documentation to confirm pinout, temperature range, and tape-and-reel specifications. Ensure compatibility with required operating temperatures and packaging formats before integration into production designs.

Selection Notes

Select this component when a single +5V supply is available but traditional dual-voltage RS-232 levels are required. It is appropriate for noise-sensitive environments due to receiver hysteresis and offers superior ESD robustness compared to standard non-E versions.

Part Context

This part belongs to the HIN2xxE family of RS-232 transceivers from Renesas (formerly Intersil). The family shares common architecture including charge-pump technology and ESD protection, differing primarily in the number of drivers and receivers provided within the same package footprint.

Replacement Considerations

Direct functional substitutes include other members of the HIN2xxE series such as HIN202E or HIN213E, provided the driver/receiver count matches the application requirements. Verify pin compatibility and electrical parameters before substitution.
