HIN208CBZ

Overview

The HIN208CBZ is a high-speed RS-232 transceiver manufactured by Renesas Electronics Corporation. It meets EIA RS-232E and V.28 specifications, operating on a single +5V power supply with onboard charge pumps generating ±10V. The device features eight drivers and five receivers, supporting data rates up to 230 kbit/s. It includes ±15kV ESD protection on I/O pins, low-power shutdown mode, and TTL/CMOS compatibility. Operating temperature range is -40°C to +85°C.

Feature Summary

• Integrates eight drivers and five receivers for complex serial communication interfaces
• Provides ±15kV electrostatic discharge (ESD) protection on all RS-232 lines
• Features low-power shutdown mode to conserve energy in battery-operated systems
• Includes onboard voltage converters eliminating the need for external ±12V supplies

Applications

• High-speed modems and ISDN terminal adaptors
• Portable computers and laptop peripherals
• Industrial instrumentation and UPS systems
• Printers and terminals requiring robust serial connectivity

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm package type (SOIC-28) and lead-free status. Ensure the order matches the exact pinout configuration required for the target PCB layout. Cross-reference the manufacturer's current product status to confirm availability and lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when an application requires multiple transmit and receive channels within a single interface circuit. The HIN208CBZ is suitable for designs needing high noise immunity via hysteresis receivers and robust ESD protection. Consider the shutdown feature if power management during idle states is critical for the system's overall efficiency requirements.

Part Context

This part belongs to the HIN20xEx family of RS-232 transceivers from Renesas (formerly Intersil). These devices are designed to replace traditional dual-supply solutions by deriving internal voltages from a single +5V source. The family offers various driver/receiver combinations to suit different interface complexity levels while maintaining standard RS-232 electrical characteristics.

Replacement Considerations

Direct replacements include other members of the HIN20xE series such as HIN208ECBZ or HIN238CBZ, depending on the required number of drivers and receivers. Verify pin-to-pin compatibility and functional equivalence with datasheets from Texas Instruments (e.g., MAX208) or Analog Devices (ADM208) if sourcing from alternative suppliers.
