HIN208CB

Overview

The HIN208CB is an RS-232 transceiver from the Harris Corporation HIN20xE family, designed for high-speed serial communications. It operates on a single +5V supply and integrates onboard charge pumps to generate the required ±10V internal voltages. The device features one driver and two receivers, supporting data rates suitable for ISDN and high-speed modems. Inputs are TTL/CMOS compatible, while outputs provide slew-rate limiting. The receivers include hysteresis for noise rejection and can withstand ±30V input signals. The component is rated for commercial temperature ranges and offers ±15kV ESD protection on both drivers and receivers.

Feature Summary

• Single-supply operation with integrated charge pump generating ±10V from +5V
• High-speed transmitter circuitry optimized for improved data rate and slew rate
• Robust receiver inputs with hysteresis for enhanced noise immunity
• Integrated electrostatic discharge (ESD) protection up to ±15kV

Applications

• ISDN terminal adaptors
• High-speed modem interfaces
• Portable computer serial ports

Procurement Notes

Verify the specific suffix 'CB' against the manufacturer's official datasheet to confirm the exact temperature range and package variant. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference part numbers with authorized distributors to confirm current availability status.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are required. It is suitable for applications needing moderate drive strength and high-speed data transmission. Consider the package type and operating temperature range specified in the datasheet to match environmental constraints.

Part Context

The HIN208CB belongs to the Harris Corporation HIN20xE series of RS-232 transmitters and receivers. This family is characterized by its ability to operate from a single power supply while providing full RS-232 compliance. The devices are designed to replace traditional dual-supply solutions, simplifying power management in portable and battery-operated systems.

Replacement Considerations

Check for direct pin-compatible alternatives from Texas Instruments or other manufacturers offering similar single-supply RS-232 transceivers. Verify that substitute components maintain the same driver/receiver count and ESD protection ratings.
