HIN232EIVZ-T

Overview

The HIN232EIVZ-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics. It operates on a single +5V power supply, utilizing onboard charge pumps to generate ±10V from the 5V input. The device features two drivers and two receivers with full-duplex communication capability. It supports data rates up to 230 kb/s and includes ±15kV ESD protection on I/O pins. Operating voltage ranges from 4.5V to 5.5V, with a typical supply current of 5mA. The component functions within a temperature range of -40°C to +85°C and is housed in a TSSOP-20 package.

Feature Summary

• Integrated charge pump eliminates need for external ±12V supplies
• High electrostatic discharge protection on RS-232 I/O pins
• TTL/CMOS compatible inputs with noise-rejecting hysteresis

Applications

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

Procurement Notes

Verify the suffix IVZ corresponds to the TSSOP-20 package configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure moisture sensitivity level requirements are met for surface mount assembly processes. Cross-reference the specific revision number against the latest datasheet to confirm pinout and electrical characteristics match design specifications.

Selection Notes

Select this component when designing systems requiring RS-232 connectivity without access to negative voltage rails. The integrated charge pump simplifies board layout by reducing external capacitor count. Verify that the 230 kb/s data rate meets application timing requirements. Consider the TSSOP-20 footprint constraints during PCB layout planning.

Part Context

This part belongs to the HIN232E family of RS-232 transmitters and receivers. The family shares common architecture including single-supply operation and high ESD protection. Variants within the series differ primarily in driver/receiver counts and package types. The HIN232E specifically provides a balanced 2-driver, 2-receiver configuration suitable for standard bidirectional serial communication links.

Replacement Considerations

HIN232EIBZ-T offers identical electrical performance in a SOIC-Wide-16 package. HIN232ECBNZ provides the same functionality in an SOIC-Narrow-16 package. These alternatives maintain compatibility with existing circuit designs while accommodating different board space requirements.
