HIN208EIAZ-T

Overview

The HIN208EIAZ-T is a CMOS RS-232 transceiver from the HIN20xE family, manufactured by Renesas Electronics. It operates on a single +5V supply and integrates onboard charge pumps to generate ±10V for RS-232 signaling. The device features two drivers and two receivers with full-duplex communication capability. It supports data rates up to 230 kbps and includes ±15kV ESD protection on I/O pins. Key electrical parameters include a minimum supply voltage of 4.5V, maximum of 5.5V, and an operating temperature range of -40°C to +85°C. The package is a 16-pin SOIC-Wide.

Feature Summary

• Integrated onboard charge pump eliminates the need for external dual-voltage power supplies.
• Robust ±15kV electrostatic discharge (ESD) protection on transmitter outputs and receiver inputs.
• Low power shutdown mode significantly reduces current consumption for battery-powered applications.
• TTL/CMOS compatible inputs and outputs with hysteresis-enhanced receivers for improved noise rejection.

Applications

• Portable computers and laptops requiring high-speed serial communication.
• Industrial modems and ISDN terminal adaptors.
• Battery-operated instrumentation and UPS systems.
• Printers and terminals interfacing with mainframe or peripheral systems.

Procurement Notes

Verify the specific ordering suffix 'IAZ-T' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the procurement channel provides traceable documentation for the Renesas brand. Confirm that the SSOP/SOIC package dimensions match the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a single +5V supply is available but ±10V RS-232 levels are required. It is suitable for designs needing moderate data rates up to 230 kbps with integrated ESD protection. Compare against the HIN202E or HIN213E if different driver/receiver counts or active receiver behavior in shutdown mode are needed.

Part Context

This part belongs to the HIN20xE series of RS-232 transmitters and receivers designed for applications where traditional ±12V supplies are unavailable. The series meets EIA high-speed RS-232E and V.28 specifications. The HIN208E variant specifically offers a balanced configuration of two drivers and two receivers within a compact surface-mount package.

Replacement Considerations

Direct functional substitutes within the same family include the HIN202E, HIN206E, HIN207E, HIN211E, and HIN213E. Verify pin-to-pin compatibility and ensure the replacement part matches the required number of drivers and receivers for the specific circuit design.
