HIN232IBZ

Overview

The HIN232IBZ is a dual driver, dual receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates on a single +5V power supply with a voltage range of 4.5V to 5.5V and features onboard charge pumps generating ±10V supplies using only 0.1µF external capacitors. The device supports data rates up to 230 kb/s and includes ±15kV ESD protection on I/O pins. It is housed in a 16-SOIC package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates the need for external ±12V power supplies
• Robust electrostatic discharge protection rated at ±15kV on all RS-232 input and output pins
• TTL and CMOS compatible inputs with hysteresis receivers for improved noise rejection
• Low power consumption with typical supply current of 5mA

Applications

• High-speed RS-232 communications ports in computer systems
• Portable, mainframe, and laptop computer interfaces
• Peripheral connections for printers and terminals
• Instrumentation and UPS systems requiring serial communication

Procurement Notes

Verify the specific suffix IBZ corresponds to the 16-SOIC wide package and tape-and-reel or tube availability as required by your assembly process. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability for industrial applications.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are required. It is suitable for designs needing high-speed data transmission up to 230kb/s with integrated ESD protection. Compare against other family members like HIN202E or HIN213E if different driver/receiver counts or shutdown modes are needed.

Part Context

This part belongs to the HIN2xxE family of high-speed RS-232 transmitters and receivers from Renesas (formerly Intersil). These devices are designed to replace traditional dual-supply RS-232 chips by generating internal voltages from a single 5V source. The family offers various combinations of drivers and receivers to suit different interface requirements.

Replacement Considerations

Direct pin-compatible alternatives within the same family include HIN232ACBNZ and HIN232ECBNZ. Cross-reference with MAX3232E or SP232E series for similar functionality, ensuring voltage ranges and ESD ratings match the design specifications.
