HIN204CB

Overview

The HIN204CB is a single-driver, dual-receiver RS-232 transceiver manufactured by Harris Corporation. It operates from a single +5V power supply and integrates onboard charge pump voltage converters to generate the required ±10V internal supplies. The device meets EIA RS-232E and V.28 specifications with a data rate of 120 kbit/s. It requires external 0.1µF capacitors for the charge pumps. Key electrical characteristics include a minimum breakdown voltage of ±25V on driver outputs and ±30V tolerance on receiver inputs. The unit features TTL/CMOS input compatibility and hysteresis in receivers for noise rejection.

Feature Summary

• Integrates onboard charge pump voltage converters to generate internal ±10V supplies from a single +5V source
• Provides true TTL/CMOS input compatibility with slew-rate-limited outputs
• Features high-noise-rejection receivers with hysteresis and ±30V input protection

Applications

• Serial communication interfaces where ±12V power supplies are unavailable
• Battery-powered systems requiring single-supply operation
• Industrial control equipment needing robust RS-232 connectivity

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors (e.g., Intersil, Renesas) due to corporate acquisitions. Confirm the package type matches the specific suffix requirements for your PCB layout. Ensure that the component version aligns with current RoHS directives if applicable to your manufacturing standards.

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 prioritizing board space savings over the zero-capacitor designs like the HIN203. Verify that the 120 kbit/s data rate meets the system's communication speed requirements before finalizing the design.

Part Context

This part belongs to the HIN200-HIN213 family of +5V powered RS-232 transmitters and receivers. The family was designed to eliminate the need for dual polarity power supplies in serial communication applications. The HIN204CB specifically provides one driver and two receivers, offering a balanced configuration for standard half-duplex or simple full-duplex serial links.

Replacement Considerations

Publicly confirmed substitutes include the HIN204CN and HIN204CP from Harris/Intersil. Cross-manufacturer equivalents such as the MAX202CPE or MAX202ESE from Maxim Integrated may be considered, provided pinout and electrical parameters are verified against the original datasheet.
