HIN202IBZ

Overview

The HIN202IBZ is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates two drivers and two receivers within a single integrated circuit, supporting the RS-232 protocol. The device operates on a single 4.5V to 5.5V power supply and achieves a data rate of 120kbps. It is housed in a 16-SOIC surface-mount package with a width of 7.50mm. The component functions reliably across an operating temperature range of -40°C to +85°C. Key electrical specifications include a receiver hysteresis of 500mV, which enhances noise immunity during signal reception.

Feature Summary

• Integrates onboard charge pump circuitry to generate required positive and negative voltage supplies from a single low-voltage source
• Provides robust electrostatic discharge protection on transmitter outputs and receiver inputs
• Features receiver input hysteresis designed to improve noise rejection capabilities
• Maintains true TTL/CMOS input compatibility for direct interfacing with digital logic

Applications

• Portable computer serial communication ports
• Industrial instrumentation data links
• Modem and ISDN terminal adaptor interfaces

Procurement Notes

Verify the specific suffix IBZ against the manufacturer's current datasheet to confirm pinout and packaging dimensions match the design requirements. Ensure the ordering information aligns with the official Renesas part numbering system to avoid receiving variants with different electrical characteristics or thermal ratings. Cross-reference the document revision date to ensure compliance with current manufacturing standards.

Selection Notes

Select this component when a full-duplex RS-232 interface is required with a single 5V power supply constraint. The 120kbps data rate suits standard asynchronous communication needs. Verify that the 16-SOIC package fits the PCB footprint constraints. Consider the -40°C to +85°C industrial temperature rating if the application environment exceeds commercial limits. Confirm that the internal charge pump capacitors fit within the available board space.

Part Context

The HIN202IBZ belongs to the HIN202E family of high-speed RS-232 transmitters and receivers. This series is engineered to meet EIA RS-232E and V.28 specifications without requiring external dual-polarity power supplies. The family includes various driver and receiver combinations to accommodate diverse interface topologies. The HIN202 variant specifically provides a balanced 2-driver and 2-receiver configuration for standard bidirectional communication tasks.

Replacement Considerations

HIN202EIBZ-T is a tape-and-reel variant of the same functional device. Verify that the reel packaging meets assembly line requirements while maintaining identical electrical performance.
