HIN209CP

Overview

The HIN209CP is a dual RS-232 transmitter and receiver interface circuit manufactured by Harris Corporation. It operates from a single +5V power supply combined with an external +12V source, utilizing onboard charge pump voltage converters to generate the necessary positive and negative voltages for RS-232 signaling. The device meets EIA RS-232E and V.28 specifications, featuring three-state TTL/CMOS compatible outputs and inputs with high noise rejection capabilities. Designed for low power consumption, it includes a shutdown function to minimize energy usage when inactive.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external dual polarity supplies
• TTL and CMOS logic compatibility ensures broad integration flexibility
• Low power shutdown mode significantly reduces current draw during idle periods

Applications

• Portable computer serial communication ports
• Laptop peripheral interfaces
• Mainframe terminal connections

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the specific suffix 'CP' corresponds to the correct package type and temperature rating required for your design. Cross-reference datasheets from both original Harris documentation and current Renesas archives to confirm pinout and electrical characteristics remain consistent.

Selection Notes

Select this component when a system requires RS-232 connectivity but has limited availability of negative voltage rails. The requirement for both +5V and +12V inputs distinguishes it from single-supply variants like the HIN202. Evaluate board space constraints against the need for external capacitors, which are mandatory for the charge pump operation in this specific model.

Part Context

This part belongs to the HIN200-HIN213 family of RS-232 transceivers developed by Harris Corporation. This series was widely adopted before the company's semiconductor division transitioned to Renesas. The HIN209 specifically addresses applications needing dual receivers and drivers while managing power efficiency through integrated voltage conversion.

Replacement Considerations

Renesas Electronics is the successor manufacturer for Harris semiconductors. Check for direct cross-references within the Renesas portfolio that maintain the dual-supply (+5V/+12V) architecture. Verify that any substitute maintains the same pin configuration and electrical tolerances defined in the original Harris specification.
