HIN203CP

Overview

The HIN203CP is a single RS-232 transmitter and receiver manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing an onboard charge pump to generate the required ±10V internal supplies without external capacitors. The device meets EIA RS-232E and V.28 specifications, featuring true TTL/CMOS input compatibility and slew-rate-limited outputs. It supports data rates up to 120kbit/s and includes receivers with hysteresis for improved noise rejection.

Feature Summary

• Onboard voltage conversion eliminates the need for external capacitors
• Single +5V power supply operation simplifies circuit design
• TTL/CMOS compatible inputs ensure direct logic interfacing

Applications

• Serial communication interfaces in systems lacking ±12V supplies
• Data transmission links requiring compact board space
• Industrial control systems needing robust noise immunity

Procurement Notes

Verify the manufacturer designation carefully, as Harris Semiconductor assets were acquired by Dialog Semiconductor, which was subsequently acquired by Renesas Electronics. Confirm current production status and sourcing channels through authorized distributors or Renesas directly to ensure component authenticity and availability.

Selection Notes

Select this component when PCB real estate is limited due to its capacitor-free design. Ensure the application requires only one transmitter and one receiver channel. Verify that the system power budget accommodates the single +5V rail and that the 120kbit/s speed meets the communication requirements.

Part Context

This part belongs to the HIN200-HIN213 family of RS-232 interface circuits designed for low-power, single-supply applications. The family offers various combinations of transmitters and receivers, with the HIN203 specifically optimized for minimal external component count by integrating the charge pump capacitors internally.
