HIN207EIB

Overview

The HIN207EIB is a high-speed RS-232 transceiver manufactured by Harris Corporation, belonging to the E-series family. It operates on a single +5V power supply and utilizes onboard charge pumps to generate internal +10V and -10V rails from external 0.1µF capacitors. The device provides one driver and two receivers, meeting EIA RS-232E and V.28 specifications with a data rate up to 230kbits/s. It features ±15kV ESD protection on I/O pins, true TTL/CMOS input compatibility, and hysteresis for noise rejection. Packaged in a 24-pin PDSO (SOIC) format, it supports an operating temperature range of -40°C to +85°C.

Feature Summary

• High-speed ISDN compatible transmitter circuit with improved slew rate
• Robust ±15kV electrostatic discharge protection on RS-232 I/O pins
• Low power shutdown mode for energy conservation in battery applications
• Integrated charge pump voltage converters eliminating need for dual supplies

Applications

• ISDN terminal adaptors and high-speed modems
• Portable computers and laptop peripheral interfaces
• Instrumentation and UPS communication ports
• Printers and terminals requiring RS-232 connectivity

Procurement Notes

Verify the specific suffix 'IB' against official Intersil/Renesas documentation to confirm package type and temperature grade. Ensure ordering includes RoHS compliance confirmation if required. Cross-reference the manufacturer's current product status to determine availability and lifecycle stage before procurement.

Selection Notes

Select this component when designing systems requiring high-speed RS-232 communication without access to ±12V supplies. The HIN207EIB is suitable for applications needing one driver and two receivers with low-power shutdown capabilities. Verify that the system environment requires the industrial temperature range supported by this specific variant.

Part Context

The HIN207EIB is part of the HIN2xxxE series of RS-232 transmitters/receivers developed by Harris Corporation, later acquired by Intersil and subsequently Renesas. This family was designed to replace older components requiring dual voltage supplies, offering a simplified single-supply solution with enhanced speed and protection features for modern digital interfaces.

Replacement Considerations

Direct replacements within the same family include the HIN206E and HIN211E, which share similar pinouts and functionality but may differ in driver/receiver counts or specific electrical characteristics. Verify pin compatibility and functional equivalence before substitution.
