HIN232EIV-T

Overview

The HIN232EIV-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics. It operates from a single +5V power supply with onboard charge pumps generating ±10V. The device features two drivers and two receivers, supporting data rates up to 230 kbps. It provides ±15kV ESD protection on driver outputs and receiver inputs. Operating temperature range is -40°C to +85°C. External capacitors of 0.1µF or greater are required for the charge pump circuit.

Feature Summary

• Integrated ±15kV electrostatic discharge (ESD) protection on all RS-232 pins
• Single +5V power supply operation with onboard voltage conversion
• High-speed data transmission capability suitable for ISDN applications
• TTL/CMOS compatible inputs with hysteresis for improved noise rejection

Applications

• ISDN terminal adaptors
• High-speed modem interfaces
• Portable computer serial ports
• Industrial instrumentation systems

Procurement Notes

Verify the specific suffix 'IV' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for the target assembly process. Confirm moisture sensitivity level handling procedures during storage and soldering.

Selection Notes

Select this component when ±12V supplies are unavailable and single-supply operation is required. The integrated ESD protection makes it suitable for environments with high static discharge risk. Verify that the 230 kbps data rate meets system requirements compared to lower-speed alternatives in the HIN series.

Part Context

This part belongs to the HIN232E family of RS-232 transceivers designed for high-speed communication. The family shares common electrical characteristics but varies in pinout configuration and package options. The HIN232E variant specifically offers a balanced driver/receiver count for standard full-duplex serial communication needs.

Replacement Considerations

HIN232EIBZ-T: Pin-compatible alternative in SOIC-16 package. MAX3232E: Similar functionality but may require different capacitor values. SP232E: Comparable RS-232 transceiver with similar speed and voltage requirements.
