HIN208EIAZ

Overview

The HIN208EIAZ is a single-supply RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates onboard charge pumps to generate ±10V supplies from a single +5V source, eliminating the need for external dual-voltage rails. The device features four drivers and five receivers, supporting data rates up to 230 kbps. It provides ±15kV ESD protection on I/O pins and meets EIA high-speed RS-232E and V.28 specifications. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Single +5V power supply operation with integrated voltage conversion
• High-speed data transmission capability suitable for ISDN applications
• Robust electrostatic discharge protection on all RS-232 interfaces
• Low power shutdown mode for energy conservation in battery systems

Applications

• Portable computers and laptops requiring serial communication
• ISDN terminal adaptors and high-speed modems
• Industrial instrumentation and UPS systems
• Printers and terminals with TTL/CMOS logic levels

Procurement Notes

Verify the specific suffix 'IAZ' confirms the SSOP-28 package and lead-free RoHS compliance. Confirm the manufacturer designation as Renesas Electronics or Intersil legacy stock. Ensure the component matches the required operating temperature range of -40°C to +85°C for industrial environments.

Selection Notes

Select this component when a single +5V supply is available but ±10V internal rails are needed for RS-232 signaling. The HIN208E variant is appropriate for designs requiring four transmit channels and five receive channels. Consider the low-power shutdown feature if battery life is a critical constraint in portable equipment.

Part Context

This part belongs to the HIN202E/HIN206E/HIN207E/HIN208E/HIN211E/HIN213E/HIN232E family of RS-232 interface circuits. These devices share common architecture features such as onboard charge pumps and ESD protection, differing primarily in the number of drivers and receivers provided.

Replacement Considerations

Compatible substitutes within the same family include HIN208EIBZ (SOIC-28) and HIN208EIPZ (PDIP-28). Cross-brand equivalents may exist but require verification of pinout compatibility and electrical parameter alignment.
