HIN208EIP

Overview

The HIN208EIP is a high-speed RS-232 transmitter and receiver interface circuit manufactured by Intersil. It meets EIA high-speed RS-232E and V.28 specifications, designed for systems lacking ±12V supplies. The device operates on a single +5V power supply, utilizing onboard charge pumps to generate +10V and -10V internal rails. It features one transmitter and two receivers with ±15kV ESD protection. Key electrical parameters include a data rate of 0.23 Mbps, a supply voltage range of 4.5V to 5.5V, and an operating temperature range of -40°C to +85°C. The package is a 16-pin SOIC.

Feature Summary

• Integrated charge pump eliminates the need for external dual-voltage power supplies
• High electrostatic discharge protection rated at ±15kV on outputs and inputs
• Low power shutdown mode available to conserve energy in battery-powered applications
• True TTL/CMOS input compatibility with slew-rate-limited outputs

Applications

• Portable computers and laptop peripheral connections
• Industrial instrumentation and UPS systems
• ISDN terminal adaptors and high-speed modems

Procurement Notes

Verify the specific suffix IP indicates the 16-pin SOIC package and industrial temperature grade (-40°C to +85°C) against the manufacturer's official datasheet. Confirm RoHS compliance status and lead-free material declarations prior to ordering. Ensure the supplier provides traceable documentation matching the exact part number to avoid substitution errors.

Selection Notes

Select this component when a single +5V supply is required for RS-232 communication without external negative voltage generation. It is suitable for designs needing moderate data rates up to 0.23 Mbps with robust ESD protection. Compare pin counts and shutdown capabilities against other family members like HIN202E or HIN211E if different channel configurations are needed.

Part Context

The HIN208EIP belongs to the Intersil HIN2xxxE family of RS-232 transceivers. This series shares common architecture including onboard charge pumps and ESD protection but varies in the number of drivers and receivers. The 'E' suffix typically denotes enhanced performance or extended temperature ranges compared to older non-E variants within the same product line.

Replacement Considerations

Direct replacements within the same family include HIN208E (same function, potentially different package or temp grade). Cross-family alternatives may include HIN202E or HIN211E if channel count differences are acceptable. Verify pinout compatibility before substituting.
