HIN208CA

Overview

The HIN208CA is a single-supply RS-232 transceiver manufactured by Harris Corporation. It operates from a single +5V power supply and utilizes onboard charge pumps to generate the required ±10V levels for RS-232 signaling, eliminating the need for external dual supplies. The device meets EIA RS-232E and V.28 specifications. Key electrical characteristics include a data rate of 120 kbit/s, a typical quiescent current of 5 mA, and a low-power shutdown mode drawing approximately 1 µA. It features three-state TTL/CMOS compatible outputs and inputs with hysteresis for noise rejection.

Feature Summary

• Single +5V power supply operation with integrated onboard voltage doubler and inverter
• Compliance with EIA RS-232E and V.28 interface specifications
• Low-power shutdown function for energy conservation in battery-powered systems
• TTL/CMOS input compatibility with three-state receiver outputs

Applications

• Portable computers and laptop serial ports
• Printers and terminals requiring RS-232 communication
• Instrumentation systems needing high-speed serial data transfer

Procurement Notes

Verify manufacturer lineage as Harris Corporation assets were acquired by Renesas Technology. Confirm that the specific HIN208CA suffix denotes the commercial temperature range variant. Ensure component authenticity through authorized distribution channels given potential legacy status.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are absent. It is suitable for applications requiring 120 kbit/s data rates. Consider the HIN203 or HIN205 if external capacitors must be minimized, or the HIN213 if active receivers are needed during shutdown.

Part Context

The HIN208CA belongs to the HIN200-HIN213 family of RS-232 transceivers designed for 5V operation. This family addresses the market need for serial interfaces in portable devices where traditional dual-voltage requirements were prohibitive. The device integrates charge pumps to simplify board layout and reduce component count.

Replacement Considerations

Renesas R2M27208C is a confirmed direct replacement within the same product family lineage.
