HIN232ECBNZ

Overview

The Intersil HIN232ECBNZ is a high-speed RS-232 transceiver designed for single +5V power supply operation. It integrates onboard charge pump voltage converters to generate the required ±10V supplies from the 5V input, eliminating the need for external dual-voltage sources. The device features two drivers and two receivers, supporting data rates up to 230 kbps. It meets EIA RS-232E and V.28 specifications and includes ±15kV ESD protection on I/O pins. The package is a 16-pin SOIC-Narrow (SOIC-16). Operating temperature range is 0°C to +70°C with a maximum supply voltage of 5.5V.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage doubler and inverter
• High-speed data transmission capability suitable for ISDN and high-speed modem applications
• Robust electrostatic discharge protection rated at ±15kV on RS-232 I/O pins
• TTL/CMOS compatible inputs with slew-rate-limited outputs and current limiting

Applications

• Portable computers, mainframes, and laptops requiring high-speed RS-232 communication ports
• Peripheral devices such as printers and terminals
• Instrumentation systems and uninterruptible power supplies (UPS)
• Modems and ISDN terminal adaptors

Procurement Notes

Verify the manufacturer designation, as Renesas Electronics acquired Intersil's semiconductor business. Confirm the specific suffix 'CBNZ' indicates the lead-free, RoHS-compliant variant in the narrow SOIC package. Ensure the datasheet version matches the production lot requirements for interface compatibility and electrical characteristics.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required without external negative voltage generation. It is appropriate for designs needing moderate speed up to 230 kbps with built-in ESD protection. Compare against the HIN232A if lower power consumption is critical, or the HIN202 series if different driver/receiver counts are needed.

Part Context

The HIN232ECBNZ belongs to the HIN232E family of RS-232 transmitters and receivers. This family was redesigned to improve data rate and slew rate compared to earlier generations. It shares architectural similarities with the HIN202E and HIN206E but offers specific driver and receiver configurations tailored for general-purpose serial communication interfaces.

Replacement Considerations

Public confirmed substitutes include the ICL3232ECBNZ from Renesas/Intersil, which offers similar functionality with 3V to 5.5V operation. The HIN232ACBNZ is a related variant within the same product line.
