HIN202EIA

Overview

The HIN202EIA is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Harris Corporation, part of the HIN202E family. It complies with EIA RS-232E and V.28 specifications, supporting data rates up to 230 kbps for ISDN and modem applications. The device operates on a single +5V supply, utilizing an onboard charge pump to generate ±10V rails from external 0.1µF capacitors. It integrates two drivers and two receivers with ±15kV ESD protection on I/O pins. Key electrical parameters include a 4.5V to 5.5V supply range, 5mA typical operating current, and -40°C to +85°C industrial temperature rating.

Feature Summary

• Single +5V power supply operation eliminates the need for external ±12V sources through integrated charge pump voltage conversion.
• High-speed performance with redesigned transmitter circuits supports data rates up to 230 kbps suitable for ISDN systems.
• Robust electrostatic discharge protection rated at ±15kV on all RS-232 input and output pins per IEC61000 standards.
• Low power shutdown mode significantly reduces current consumption to approximately 1µA for battery-powered efficiency.

Applications

• ISDN terminal adaptors requiring high-speed serial communication
• Portable computers and laptop peripheral interfaces
• Industrial instrumentation and UPS systems
• High-speed modems and printer connections

Procurement Notes

Verify the manufacturer origin carefully as Harris Corporation's semiconductor assets were acquired by Intersil, which was subsequently acquired by Renesas Electronics. Ensure the component matches the specific HIN202EIA suffix requirements for package type and temperature grade. Confirm RoHS compliance status and lead-free annealing details against current datasheets to avoid obsolete stock issues.

Selection Notes

Select this component when designing systems limited to a single +5V power rail but requiring standard RS-232 signaling levels. It is appropriate for applications needing moderate speed (up to 230kbps) rather than ultra-high baud rates. Consider the SOIC-16 package constraints and ensure adequate PCB space for the required 0.1µF charge pump capacitors near the V+ and V- pins.

Part Context

This device belongs to the HIN202E family of RS-232 transceivers developed originally by Harris Semiconductor. The family includes variants like HIN206E and HIN213E with different driver/receiver counts or shutdown features. The HIN202EIA specifically denotes the industrial temperature grade version in a 16-pin SOIC package, serving as a bridge between TTL/CMOS logic and RS-232 voltage levels.

Replacement Considerations

Direct replacements within the same family include HIN202EIBNZ-T (Intersil/Renesas equivalent). Cross-manufacturer alternatives such as MAX202E or SP3232EE may require pinout verification and capacitor value adjustments due to differing internal charge pump architectures.
