HIN208EIBZ

Overview

The HIN208EIBZ is a dual transmitter and dual receiver RS-232 interface circuit manufactured by Renesas Electronics Corporation. It operates on a single +5V power supply, utilizing onboard charge pumps to generate the required positive and negative voltages for RS-232 signaling without external high-voltage sources. The device meets EIA high-speed RS-232E and V.28 specifications, supporting data rates up to 230 kbps. It features ±15kV electrostatic discharge (ESD) protection on I/O pins, TTL/CMOS input compatibility, and hysteresis in receivers for improved noise rejection. The component is housed in a 16-pin SOIC-Wide package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage converters
• High-speed data transmission capability suitable for ISDN and modem applications
• Robust ±15kV ESD protection on all RS-232 transmitter and receiver pins
• TTL/CMOS compatible inputs with slew-rate limited outputs for signal integrity

Applications

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

Procurement Notes

Verify the specific suffix 'IBZ' against the manufacturer's current datasheet to confirm pinout and packaging dimensions match the design requirements. Ensure that the 16-SOIC-Wide package footprint aligns with the PCB layout. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Check for any recent product change notices regarding material composition or manufacturing location changes.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with high ESD tolerance and single-supply convenience. It is appropriate for designs where generating ±12V is impractical. Compare data rate requirements against the 230 kbps limit. Consider the HIN202E or HIN213E if different driver/receiver counts or shutdown modes are needed instead.

Part Context

The HIN208EIBZ belongs to the HIN20xE family of RS-232 transceivers from Renesas (formerly Intersil). This family shares common architecture features such as the onboard charge pump and ESD protection but varies in the number of drivers and receivers. The HIN208E specifically provides two drivers and two receivers, distinguishing it from single-driver or quad-driver variants in the same series.

Replacement Considerations

Direct functional substitutes within the same family include the HIN202EIBZ, HIN206EIBZ, HIN211EIBZ, and HIN213EIBZ. Verify that the alternative part number matches the required number of drivers and receivers. Ensure the replacement maintains the same SOIC-16 package and electrical characteristics.
