HIN201CB

Overview

The HIN201CB is a dual transmitter and dual receiver RS-232 interface circuit manufactured by Harris Corporation. It meets EIA RS-232E and V.28 specifications, designed for applications where standard ±12V supplies are unavailable. Unlike other members of the HIN200-HIN213 family that operate on a single +5V supply, the HIN201CB requires both +5V and +12V power rails. The device integrates onboard charge pump voltage converters to generate the necessary internal voltages from the external supplies. It features true TTL/CMOS input compatibility, slew-rate-limited outputs, and receivers with hysteresis for improved noise rejection.

Feature Summary

• Dual transmitters and dual receivers integrated into a single package
• Onboard charge pump voltage converters for internal supply generation
• True TTL/CMOS input compatibility with slew-rate-limited outputs
• Receivers feature hysteresis to enhance noise rejection capabilities

Applications

• RS-232 serial communication interfaces in systems lacking dedicated ±12V power rails
• Industrial control equipment requiring robust noise immunity
• Data acquisition systems interfacing microcontrollers with RS-232 ports

Procurement Notes

Verify the specific suffix 'CB' against the manufacturer's current datasheet to confirm temperature range and package type. Ensure the design supports both +5V and +12V inputs, as this variant differs from the single-supply HIN200 series. Confirm RoHS compliance status if required for the target assembly process.

Selection Notes

Select the HIN201CB when the application specifically requires two drivers and two receivers but cannot utilize the single-supply architecture of the HIN203 or HIN205. This part is appropriate when the system already provides a +12V rail alongside the standard +5V logic supply, eliminating the need for an external voltage doubler while maintaining full RS-232 compliance.

Part Context

The HIN201CB belongs to the HIN200-HIN213 family of +5V powered RS-232 transceivers. While most devices in this family operate solely on a +5V supply using internal charge pumps, the HIN201 and HIN209 variants are distinct exceptions requiring an additional +12V supply. This family was designed to simplify RS-232 interface design by reducing external component count compared to older discrete solutions.
