HIN231CP

Overview

The HIN231CP is a low-power, dual RS-232 transceiver manufactured by Harris Corporation. It features an internal charge pump that operates from a single +5V supply, eliminating the need for external negative voltage sources. The device includes two drivers and two receivers, providing full RS-232 compliance with EIA/TIA-232-E and ITU-T V.28 standards. Key electrical parameters include a driver output voltage range of ±5V to ±15V and a receiver input threshold of ±3V. The unit is available in a 16-pin DIP package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Internal charge pump eliminates requirement for external negative supply voltages
• Dual drivers and dual receivers support simultaneous bidirectional communication
• Low power consumption design suitable for battery-operated systems

Applications

• Point-to-point serial communication links
• Modem interface circuits
• Portable data terminals

Procurement Notes

Verify the manufacturer designation on the component marking, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the part number suffix matches the specific package type and temperature grade required for your application. Cross-reference with current Renesas documentation to confirm availability and final specifications.

Selection Notes

Select this component when a dual-channel RS-232 solution is needed with minimal external passive components. The integrated charge pump simplifies board layout by removing inductors or switching regulators typically required for negative rail generation. Confirm that the single +5V supply constraint aligns with your system power architecture before finalizing the design.

Part Context

This component belongs to the family of standard RS-232 line drivers and receivers. It was originally produced by Harris Semiconductor before the acquisition of its assets. The device serves as a bridge between microprocessor logic levels and RS-232 signal levels, facilitating reliable data transmission over short distances in industrial and commercial environments.

Replacement Considerations

Renesas RH1231CP is the direct successor part following the asset acquisition. Other compatible alternatives include MAX232CPE and ST232ECPE, provided pin compatibility and electrical specifications are verified against the original datasheet.
