HIN202EIBNZ

Overview

The HIN202EIBNZ is a full-duplex RS-232 transceiver integrated circuit manufactured by Renesas Electronics Corporation. It complies with EIA high-speed RS-232E and V.28 specifications, supporting data rates up to 230 kbps. The device operates on a single +5V power supply (4.5V to 5.5V range) and includes onboard charge pump voltage converters to generate the required ±10V levels without external transformers. It features two drivers and two receivers housed in a 16-SOIC package. Key electrical parameters include ±15kV ESD protection on I/O pins, a typical operating current of 5mA, and an operating temperature range from -40°C to +85°C.

Feature Summary

• Redesigned transmitter circuit enhances data rate and slew rate for ISDN and high-speed modem compatibility
• Integrated onboard charge pump eliminates need for dual polarity power supplies or external transformers
• Robust electrostatic discharge protection on RS-232 input and output pins ensures signal integrity
• Low power shutdown mode significantly reduces energy consumption in battery-powered systems

Applications

• ISDN terminal adaptors requiring high-speed serial communication
• High-speed modem interfaces in portable and mainframe computers
• Peripheral connections for printers and terminals
• Instrumentation and uninterruptible power supply (UPS) control ports

Procurement Notes

Verify the specific suffix 'B' indicates the SOIC-Wide (7.5mm) package variant rather than the narrow version. Confirm RoHS compliance status through official Renesas documentation as manufacturing processes evolve. Ensure the ordering code matches the exact pinout and thermal requirements for the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require high-speed RS-232 communication but lack access to negative voltage rails. The internal charge pump simplifies board design by removing external inductors. Consider the 16-SOIC footprint constraints and verify that the 230kbps speed meets the application's timing requirements compared to standard 120kbps alternatives.

Part Context

This part belongs to the HIN202E family of RS-232 transceivers originally developed by Intersil and now produced by Renesas. The 'E' designation signifies enhanced features such as higher data rates and improved ESD protection compared to earlier generations. It serves as a direct replacement for legacy components in industrial and commercial serial communication equipment.

Replacement Considerations

Compatible substitutes within the same family include HIN202EIBZ and HIN202EIBZR. Verify pin-to-pin compatibility and package dimensions (SOIC-Wide vs. SOIC-Narrow) when swapping between these variants to ensure mechanical fit.
