HIN232EIBNZ

Overview

The HIN232EIBNZ is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Renesas Electronics. It meets EIA RS-232E and V.28 specifications, designed for systems lacking ±12V supplies. The device operates on a single +5V power supply with onboard charge pumps generating ±10V. Key electrical parameters include a data rate of 230 kbps, a typical operating current of 5 mA, and propagation delay of 4000 ns. It features ±15kV ESD protection on I/O pins, 300Ω power-off source impedance, and requires only 0.1µF external capacitors. The component supports full-duplex communication in a 16-SOIC package.

Feature Summary

• Integrated onboard voltage doubler and inverter eliminates the need for external ±12V power rails.
• High electrostatic discharge (ESD) protection rated at ±15kV on transmitter outputs and receiver inputs.
• Low power consumption design with typical active current of 5 mA and minimal standby requirements.
• Enhanced noise rejection capabilities through receiver input hysteresis and TTL/CMOS compatible inputs.

Applications

• ISDN terminal adaptors requiring high-speed serial communication
• Portable computers, laptops, and mainframe peripheral connections
• Industrial instrumentation and uninterruptible power supply (UPS) interfaces
• High-speed modem applications

Procurement Notes

Verify the specific suffix IBNZ to confirm the SOIC-16 narrow package and industrial temperature range (-40°C to +85°C). Ensure compatibility with existing PCB footprints for 16-pin surface-mount devices. Confirm RoHS compliance status via the manufacturer's latest documentation before integration into regulated assemblies.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are required. It is suitable for replacing legacy parts like the MAX232 where higher data rates up to 230 kbps are needed. Consider the HIN232E family variants if different driver/receiver counts or shutdown modes are necessary for the specific system architecture.

Part Context

This part belongs to the HIN232E family of RS-232 transceivers from Renesas (formerly Intersil). The family shares common architecture but varies in driver/receiver configurations and power management features. The HIN232EIBNZ specifically denotes the version with two drivers and two receivers optimized for general-purpose high-speed serial links.

Replacement Considerations

Direct pin-compatible replacements within the same family include HIN232ECBNZ for commercial temperature ranges. Cross-family alternatives like the ICL3232 offer similar functionality but may differ in voltage tolerance and current consumption profiles.
