HIN232EIVZ

Overview

The HIN232EIVZ is a dual RS-232 transceiver manufactured by Intersil, designed for single-supply operation. It operates within a voltage range of 4.5 V to 5.5 V and supports data rates up to 120 kbps. The device integrates onboard charge pumps to generate the required ±10 V supplies from a single +5 V source, eliminating the need for external dual rails. It features two drivers and two receivers with full-duplex communication capability. The component includes ±15 kV ESD protection on I/O pins and operates across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump circuitry generates internal ±10 V supplies from a single +5 V power source.
• Transmitter outputs and receiver inputs are protected against electrostatic discharge up to ±15 kV.
• Receivers incorporate hysteresis to enhance noise rejection in electrically noisy environments.

Applications

• Industrial control systems requiring robust serial communication interfaces
• Battery-powered equipment where dual voltage supplies are unavailable
• High-speed modem connections and ISDN compatible devices

Procurement Notes

Verify the specific suffix 'IVZ' corresponds to the TSSOP-20 package and industrial temperature grade when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering information matches the exact manufacturer part number to avoid pinout or electrical specification mismatches during procurement.

Selection Notes

Select this component when a single +5 V supply is available but standard RS-232 voltage levels are required. It is suitable for applications needing moderate data rates up to 120 kbps with high ESD immunity. Compare against higher-speed variants if baud rates exceed 120 kbps or if different package constraints apply.

Part Context

This device belongs to the HIN232 family of RS-232 transmitters and receivers. The family is characterized by meeting EIA high-speed RS-232E and V.28 specifications while operating from a single supply. It shares core architectural features with related models like the HIN202E and HIN213E, differing primarily in driver/receiver counts and specific interface configurations.

Replacement Considerations

Direct functional substitutes include the HIN232CN (PDIP) and HIN232IN (SOIC). Verify that alternative packages maintain the same pinout compatibility and electrical characteristics, specifically the 120 kbps data rate limit and ±15 kV ESD protection ratings.
