HIN203CB

Overview

The HIN203CB is an RS-232 transceiver from the HIN200-HIN213 family, manufactured by Harris Corporation. It meets EIA RS-232E and V.28 specifications while requiring only a single +5V power supply. The device features onboard charge pump voltage converters that generate +10V and -10V supplies internally. A key characteristic of the HIN203 variant is that it requires no external capacitors for operation. It supports a data rate of 120kbit/s and includes three-state TTL/CMOS receiver outputs with ±30V input voltage range capability.

Feature Summary

• Onboard charge pump eliminates need for external capacitors
• Single +5V power supply operation
• Meets EIA RS-232E and V.28 specifications

Applications

• Computer serial ports
• Portable and laptop systems
• Printers and terminals

Procurement Notes

Verify the manufacturer designation carefully, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas Electronics. Confirm the specific suffix 'CB' corresponds to the required temperature grade and package type in official datasheets. Ensure compatibility with current supply chain sources for legacy components.

Selection Notes

Select this component when board space is critical due to the absence of external capacitor requirements. It is suitable for applications where only a +5V supply is available, avoiding the need for dual voltage rails. Compare against HIN205 if similar functionality is needed, ensuring the pinout and driver/receiver configuration matches the design requirements.

Part Context

This part belongs to the HIN200-HIN213 family of RS-232 interface circuits designed for low-power, single-supply applications. The family provides various transmitter and receiver combinations to accommodate different communication needs while maintaining compatibility with standard RS-232 protocols.

Replacement Considerations

Check for equivalents from Renesas or Intersil, such as the ISL2103 series, which may offer updated manufacturing processes. Verify electrical parameters like slew rate and input impedance to ensure functional parity with the original Harris specification.
