HIN205CP

Overview

The HIN205CP is a single RS-232 transmitter/receiver manufactured by Harris Corporation. It operates from a single +5V power supply and utilizes onboard charge pump circuitry to generate the required ±10V internal voltages, eliminating the need for external dual supplies. The device meets EIA RS-232E and V.28 specifications with a data rate of 120kbit/s. It requires no external capacitors, making it suitable for space-constrained designs. The package is an 8-pin DIP.

Feature Summary

• Integrated onboard voltage doubler and inverter generates ±10V from a single +5V source
• Eliminates requirement for external charge pump capacitors
• Provides three-state TTL/CMOS compatible receiver outputs
• Includes output current limiting and low power shutdown functionality

Applications

• Portable computer serial communication ports
• Laptop peripheral interfaces
• Printers and terminals requiring RS-232 connectivity

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities such as Intersil or Renesas. Confirm the specific suffix 'CP' corresponds to the commercial temperature range and PDIP-8 package configuration. Ensure compliance with relevant RoHS directives if applicable to the production batch.

Selection Notes

Select this component when a single +5V supply is available and board space for external capacitors is limited. It serves as a direct replacement for legacy RS-232 transceivers requiring dual supplies. Verify that the 120kbit/s data rate satisfies the system requirements.

Part Context

This part belongs to the HIN200-HIN213 family of RS-232 interface circuits designed for systems lacking ±12V power rails. The family offers various driver/receiver combinations. The HIN205 specifically provides one driver and one receiver without external capacitors.
