HIN232ECP

Overview

The HIN232ECP 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 lacking ±12V supplies. The device operates on a single +5V power supply, utilizing onboard charge pump voltage converters to generate +10V and -10V internal rails. Key electrical parameters include a data rate of 230kbit/s, typical low power consumption of 5mA, and an operating temperature range of 0°C to +70°C. It requires only 0.1µF or greater external capacitors for the charge pump.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external ±12V power supplies
• High-speed data transmission capability up to 230kbit/s
• TTL/CMOS compatible inputs with slew-rate-limited outputs
• Receivers feature hysteresis to improve noise rejection

Applications

• Portable computers and laptops requiring RS-232 communication ports
• Peripheral connections for printers and terminals
• Instrumentation systems and UPS units
• Modem interfaces

Procurement Notes

Verify the specific suffix 'CP' against official Harris or Renesas documentation to confirm package type and temperature grade. Ensure the component source matches the original manufacturer's specifications for RS-232 compliance and electrical characteristics before integration.

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 needing high data rates up to 230kbit/s without complex external power generation circuits. Verify that the package style matches the PCB layout requirements.

Part Context

This part belongs to the HIN200-HIN213 family of RS-232 transmitters/receivers originally developed by Harris Corporation, now under Renesas. These devices are designed to replace traditional dual-supply RS-232 solutions by integrating voltage conversion on-chip, simplifying system design for portable and battery-operated equipment.

Replacement Considerations

HIN232ACBNZ is a documented RoHS-compliant variant within the same functional family.
