HIN207CA

Overview

The HIN207CA is a +5V powered RS-232 transmitter/receiver interface circuit from the HIN200-HIN213 family, manufactured by Harris Corporation. It meets EIA RS-232E and V.28 specifications, utilizing onboard charge pump voltage converters to generate ±10V supplies from a single +5V source. The device features one driver and three receivers with true TTL/CMOS input compatibility. Key electrical parameters include a data rate of 120 kbit/s, a maximum supply voltage of 5.25 V, and a minimum of 4.75 V. It operates within a temperature range of -40°C to +85°C, consumes 20 mA of operating current, and requires external 0.1 µF capacitors for the charge pump.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external ±12V power supplies.
• Drivers feature slew rate-limited outputs and 300Ω power-off source impedance.
• Receivers incorporate hysteresis to significantly improve noise rejection capabilities.
• Inputs are protected against high voltages up to ±30V.

Applications

• Portable computers and laptop peripheral connections
• Mainframe computer communication ports
• Instrumentation and UPS systems
• ISDN terminal adaptors and high-speed modems

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for lead-free annealing availability. Review datasheet revisions for any pinout or electrical specification updates. Ensure storage conditions account for moisture sensitivity levels prior to soldering.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are absent. Compare against HIN206E or HIN208E if different driver/receiver counts are required. Verify that the 120 kbit/s data rate suffices for the target application. Check package options such as SOIC or DIP based on board space constraints.

Part Context

This part belongs to the HIN200 series of RS-232 transceivers originally developed by Harris Semiconductor. The series was later acquired by Intersil and subsequently Renesas Electronics. The HIN207CA represents an earlier generation compared to the 'E' suffix variants which offer higher speeds and ESD protection.

Replacement Considerations

• HIN207EIBZ-T
• MAX207CPE
