HIN208EIB

Overview

The HIN208EIB is a high-speed RS-232 transceiver manufactured by Renesas Electronics Corporation, belonging to the HIN20xE family. It operates from a single +5V supply and utilizes onboard charge pumps to generate ±10V internal supplies, eliminating the need for external dual-voltage sources. The device features three drivers and two receivers with true TTL/CMOS input compatibility. It meets EIA RS-232E and V.28 specifications, supporting data rates up to 230 kbits/s. The component includes ±15kV ESD protection on I/O pins and offers a low-power shutdown mode for energy conservation in battery-powered applications.

Feature Summary

• Onboard charge pump voltage converters generate required positive and negative supplies from a single +5V source
• Integrated ±15kV electrostatic discharge protection on transmitter outputs and receiver inputs
• Low power shutdown mode designed to conserve energy in portable or battery-operated systems
• Receiver inputs feature hysteresis to significantly improve noise rejection capabilities

Applications

• Portable computer serial communication ports
• High-speed modem interfaces
• ISDN terminal adaptors
• Industrial instrumentation serial links

Procurement Notes

Verify the specific suffix 'IB' against official Renesas documentation to confirm package type and temperature range. Ensure the ordering code matches the exact pin configuration and RoHS compliance status required for the design. Cross-reference the manufacturer's current datasheet revision to validate availability and final electrical characteristics before procurement.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are absent. It is suitable for designs requiring moderate data rates up to 230 kbps. Consider the shutdown functionality if power management is critical. Verify that the number of drivers and receivers meets the interface requirements without needing additional logic gates.

Part Context

This part belongs to the HIN20xE series of RS-232 transmitters and receivers developed by Intersil, now part of Renesas Electronics. The series was designed to replace older components requiring complex dual-supply configurations. It shares architectural similarities with the HIN206E and HIN211E, differing primarily in the number of integrated drivers and receivers within the same package footprint.

Replacement Considerations

Official substitutes include other members of the HIN20xE family such as the HIN206EIB or HIN211EIB, provided the driver/receiver count aligns with system needs. Verify pin-to-pin compatibility and electrical parameter equivalence in the official selection guide before substitution.
