HIN232ECBNZ-T

Overview

The HIN232ECBNZ-T 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 (4.5V to 5.5V) with onboard charge pumps generating ±10V using only 0.1µF external capacitors. It features a data rate of 230 kbps, ±15kV ESD protection on I/O pins, and low power consumption of typically 5mA. The package is SOIC-Narrow-16 with a pitch of 1.3mm.

Feature Summary

• Integrated charge pump voltage converter eliminates need for dual polarity power supplies
• Robust electrostatic discharge protection on transmitters and receivers
• High-speed data transmission capability suitable for ISDN applications
• Low power shutdown mode for energy conservation in battery-operated devices

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 RS-232 ports

Procurement Notes

Verify the component authenticity through authorized Renesas distributors or certified suppliers. Confirm the RoHS compliance status and Pb-Free designation matches the specific batch requirements. Ensure the SOIC-Narrow-16 package dimensions align with PCB footprint designs. Check for moisture sensitivity level (MSL) ratings if reflow soldering is planned. Validate that the ordering suffix corresponds to the tape-and-reel packaging format indicated by the 'T' designation.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required. It is appropriate for designs needing ±15kV ESD protection without external clamping diodes. Choose this part over standard RS-232 transceivers if board space is limited due to the requirement for only 0.1µF capacitors. Consider the 230 kbps data rate for compatibility with ISDN and modem applications. Verify thermal performance within the specified operating temperature range for the intended environment.

Part Context

The HIN232ECBNZ-T belongs to the HIN232E family of RS-232 transmitters and receivers from Renesas (formerly Intersil). This family shares common architecture including onboard voltage converters and ESD protection. Variants within the family differ primarily in the number of drivers and receivers, such as the HIN202E or HIN213E. The 'CBNZ' suffix indicates the SOIC-Narrow-16 package and RoHS compliance, while '-T' denotes tape-and-reel packaging.

Replacement Considerations

Direct substitutes include other members of the HIN232E family like the HIN232ACBNZ, provided pinout and functionality match. Cross-reference with Intersil legacy datasheets for equivalent part numbers. Ensure any replacement maintains the 230 kbps speed and ±15kV ESD rating. Verify package compatibility for SOIC-Narrow-16 mounting.
