HIN208ECA-T

Overview

The HIN208ECA-T is a high-speed RS-232 transceiver manufactured by Intersil, designed for single +5V power supply operation. It integrates onboard charge pump voltage converters to generate the required ±10V supplies from the 5V input, eliminating the need for external dual-voltage sources. The device features two drivers and two receivers, supporting data rates up to 230 kbps. It provides ±15kV ESD protection on RS-232 I/O pins in compliance with IEC61000 standards. The component operates within a temperature range of -40°C to +85°C and utilizes a 20-pin SOIC package.

Feature Summary

• Integrated onboard charge pump eliminates requirement for external ±12V power supplies
• High-speed transmitter circuit supports ISDN and modem applications up to 230 kbps
• Robust electrostatic discharge protection rated at ±15kV on all RS-232 interfaces
• Low power shutdown mode available for energy conservation in battery-powered systems

Applications

• ISDN terminal adapters requiring high-speed serial communication
• Battery-operated equipment utilizing low-power shutdown capabilities
• Computer peripheral interfaces and printer connections
• Industrial instrumentation with limited power supply options

Procurement Notes

Verify the specific suffix 'CA' against official Intersil documentation to confirm package width and tape/reel specifications. Ensure compatibility with RoHS requirements if lead-free annealing is mandated for the assembly process. Cross-reference the manufacturer part number with current Renesas Electronics listings as Intersil operations have been integrated into the broader portfolio.

Selection Notes

Select this component when designing systems that require full-duplex RS-232 communication without access to negative voltage rails. The HIN208ECA-T is appropriate for applications needing two independent transmit and receive channels. Consider the 20-pin SOIC footprint during PCB layout planning. Verify that the 230 kbps data rate meets the system timing requirements compared to slower standard RS-232 devices.

Part Context

This device belongs to the HIN20xE family of RS-232 transmitters and receivers developed by Intersil. The family shares common architecture including onboard voltage conversion and ESD protection but varies in driver/receiver counts and shutdown features. The HIN208ECA-T specifically offers a balanced configuration of two drivers and two receivers suitable for general-purpose serial interface tasks.

Replacement Considerations

Direct substitutes include other members of the HIN20xE series such as the HIN202E or HIN206E, provided pinout and functional requirements match. Check datasheets for equivalent ESD ratings and operating temperature ranges before substitution.
