HIN200CB-T

Overview

The HIN200CB-T is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Harris Corporation. It meets all EIA RS-232E and V.28 specifications, designed for systems where ±12V supplies are unavailable. The device operates from a single +5V power supply using onboard charge pump voltage converters to generate the required ±10V levels. It features three drivers and two receivers with TTL/CMOS compatible inputs. Key electrical parameters include a data rate of 120kbit/s, low power consumption of typically 5mA, and a shutdown current of approximately 1µA. The package type is CB.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external dual-voltage supplies
• TTL and CMOS compatible input logic levels ensure broad digital interface compatibility
• Low power shutdown function significantly reduces standby current consumption
• Integrated output current limiting protects against short circuits and overloads

Applications

• Portable computers and laptop serial communication ports
• Mainframe computer peripheral connections
• Printers and terminal interfaces requiring RS-232 signaling
• Instrumentation systems with limited power supply options

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities, as corporate acquisitions may affect part sourcing. Confirm the specific suffix 'CB-T' corresponds to the correct temperature range and packaging variant. Ensure the component meets current environmental compliance standards relevant to the deployment region. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required. It is suitable for applications prioritizing low power consumption due to the shutdown feature. Consider the 120kbit/s data rate limit for high-speed serial links. Verify that the package dimensions fit the target PCB layout constraints compared to alternative SOIC or DIP packages.

Part Context

The HIN200 series belongs to a family of RS-232 transceivers designed to simplify interface design by integrating charge pumps. This specific model provides three drivers and two receivers, offering flexibility for complex serial connections. The technology represents a standard solution for legacy serial communication in modern low-voltage digital systems.
