HIN202IB

Overview

The HIN202IB is a full-duplex RS-232 transceiver manufactured by Harris Corporation, 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 120 kbps. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 16-pin SOIC package with a width of 7.50 mm. The component meets EIA RS-232E and V.28 specifications.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage converters generating ±10V supplies
• Transmitter outputs and receiver inputs protected against ±15kV electrostatic discharge (ESD)
• Receivers feature 0.5V hysteresis to significantly improve noise rejection capabilities
• Drivers provide true TTL/CMOS input compatibility with slew rate-limited outputs

Applications

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

Procurement Notes

Verify the manufacturer origin carefully, as the HIN202 series was originally developed by Harris Corporation before being acquired by Intersil and subsequently Renesas Electronics. Ensure the specific suffix matches the required package type and temperature rating. Confirm RoHS compliance status, as older Harris-branded inventory may not meet current environmental directives compared to modern equivalents.

Selection Notes

Select this component when designing systems limited to a single +5V power rail without access to ±12V supplies. The HIN202IB is suitable for applications requiring moderate data speeds up to 120 kbps. Consider the HIN202E variant if an extended industrial temperature range (-40°C to +85°C) or higher data rates (230 kbps) are required. Verify that the 16-SOIC package dimensions fit the target PCB layout constraints.

Part Context

The HIN202IB belongs to the broader HIN200-HIN213 family of RS-232 interface circuits. This family shares common architectural features such as onboard charge pumps and single-supply operation but varies in the number of drivers and receivers. The 'IB' suffix typically denotes the commercial temperature grade and SOIC packaging, distinguishing it from industrial variants like the HIN202EIBZ.

Replacement Considerations

The HIN202EIBZ is a direct functional successor from Renesas/Intersil, offering improved performance with 230 kbps data rates and an extended temperature range. Other compatible replacements include the MAX202E and SP3232EE, which maintain pin compatibility while providing updated manufacturing support.
