HIN232ACBZ

Overview

The HIN232ACBZ is a high-speed, +5V powered RS-232 transmitter/receiver manufactured by Renesas Electronics. It meets EIA RS-232E and V.28 specifications, utilizing an onboard charge pump to generate ±10V supplies from a single +5V source. The device features two drivers and two receivers with true TTL/CMOS input compatibility. Key electrical parameters include a data rate of 230 kbit/s, typical supply current of 5 mA, and ±10V output swing. It offers ±15kV ESD protection on bus pins, ±30V receiver input range, and 300Ω power-off source impedance. The component operates within a commercial temperature range of 0°C to +70°C and requires external 0.1µF capacitors for the charge pump.

Feature Summary

• Integrated onboard voltage doubler and inverter eliminates need for external ±12V supplies
• High-speed data transmission capability up to 230 kbit/s for modem and ISDN applications
• Robust noise rejection through receiver hysteresis and wide input voltage tolerance
• Enhanced system reliability via ±15kV electrostatic discharge protection on communication lines

Applications

• High-speed RS-232 communications ports in computer systems
• Portable computers, laptops, and mainframe peripherals
• Printers, terminals, and instrumentation equipment
• Uninterruptible Power Supplies (UPS) and modem interfaces

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required temperature grade and pin configuration. Cross-reference with authorized distributors to validate authenticity and traceability. Confirm that the component meets all relevant environmental regulations for the target deployment region.

Selection Notes

Select this component when designing systems requiring high-speed RS-232 connectivity without access to dual polarity power rails. It is suitable for replacing older Harris Semiconductor parts with improved ESD protection. Consider the 230 kbit/s data rate limit for bandwidth requirements. Verify that the SOIC-16 package fits the PCB layout constraints and thermal management needs of the application.

Part Context

The HIN232ACBZ belongs to the HIN232E family of RS-232 transceivers designed for +5V operation. This family addresses the need for high-speed serial communication in portable and battery-powered devices where traditional ±12V supplies are unavailable. The device integrates charge pump circuitry to simplify board design and reduce component count compared to legacy solutions.

Replacement Considerations

Direct replacements may include other members of the HIN232E family or equivalent RS-232 transceivers from other manufacturers. Verify pin compatibility and electrical specifications before substitution. Ensure that any alternative component supports the same data rate and ESD protection levels.
