HIN208ECAZ

Overview

The HIN208ECAZ is a high-speed RS-232 transceiver from the HIN208E family, manufactured by Renesas Electronics. It operates on a single +5V supply and includes onboard charge pumps to generate ±10V rails. The device features two drivers and two receivers with ±15kV ESD protection on I/O pins. It meets EIA RS-232E and V.28 specifications, supporting data rates up to 230 kbps. Key electrical parameters include a supply voltage range of 4.5V to 5.5V, shutdown current of 15μA (disabled), and operating temperature of -40°C to +85°C. The package is SSOP with 28 leads.

Feature Summary

• Integrated charge pump generates internal ±10V supplies from a single +5V source
• High ESD protection rated at ±15kV on transmitter outputs and receiver inputs
• Low power shutdown mode for energy conservation in battery applications
• Slew rate-limited outputs reduce electromagnetic interference

Applications

• Portable computers and laptops requiring RS-232 connectivity
• ISDN terminal adaptors and high-speed modems
• Industrial instrumentation and UPS systems
• Printers and terminals with TTL/CMOS interfaces

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm pinout and package dimensions. Ensure compatibility with existing PCB footprints before procurement. Confirm RoHS compliance status for the specific manufacturing lot. Check for moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when a dual-driver, dual-receiver RS-232 interface is required with integrated voltage generation. It is suitable for designs where ±12V external supplies are unavailable. Consider the shutdown feature for power-sensitive applications. Verify that the 230 kbps data rate meets system timing requirements.

Part Context

The HIN208ECAZ belongs to the HIN2xxE family of RS-232 transceivers designed for +5V operation. This family replaces older devices requiring dual polarity supplies. The HIN208E variant specifically provides two drivers and two receivers, offering a balanced configuration for standard serial communication ports.

Replacement Considerations

Direct replacements within the same family include HIN208EC and HIN208EIAZ. Verify pin compatibility and electrical characteristics before substitution. Cross-reference with HIN202E or HIN206E only if driver/receiver counts align with design needs.
