HIN232ECAZ

Overview

The HIN232ECAZ is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Renesas Electronics Corporation. It meets EIA high-speed RS-232E and V.28 specifications, designed for systems lacking ±12V supplies. The device operates on a single +5V power supply and integrates onboard charge pump voltage converters to generate +10V and -10V rails. Key electrical parameters include a data rate of 230 kbit/s, a typical operating current of 5 mA, and an operating temperature range of 0°C to +70°C. It features ±15kV ESD protection on transmitter outputs and receiver inputs, along with true TTL/CMOS input compatibility.

Feature Summary

• Integrated onboard charge pump eliminates the need for external dual-voltage power supplies
• High-speed performance suitable for ISDN and modem applications
• Robust electrostatic discharge protection on all signal pins
• Low power consumption with shutdown mode capability

Applications

• Portable computers and laptops requiring high-speed serial communication
• ISDN terminal adaptors and high-speed modems
• Peripheral connections such as printers and terminals
• Instrumentation and UPS systems with limited voltage availability

Procurement Notes

Verify the specific suffix 'CAZ' against the official Renesas datasheet to confirm package type and RoHS compliance status. Ensure the ordering part number matches the exact pinout and functional requirements for the target design. Cross-reference with authorized distributors to confirm current production status and availability constraints.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 levels are required. It is appropriate for designs needing high data rates up to 230 kbit/s. Consider the integrated charge pump if space for large external capacitors is limited. Verify that the 0°C to +70°C commercial temperature range meets the environmental requirements of the final application.

Part Context

The HIN232ECAZ belongs to the HIN2xxE family of RS-232 transceivers from Renesas (formerly Harris). This family shares common architecture features such as single-supply operation and ESD protection. Other members like HIN202E or HIN213E offer different driver/receiver counts or additional shutdown features within the same ecosystem.

Replacement Considerations

Publicly confirmed substitutes include the ICL3223ECAZ and HIN232ACBNZ. Verify pin compatibility and electrical specifications before substitution. The ICL3223 supports 3V operation in addition to 5V, while the ACBNZ variant may differ in package style.
