HIN205ACP

Overview

The HIN205ACP is a dual RS-232 transceiver manufactured by Harris Corporation, designed for data communication applications. It integrates two drivers and two receivers on a single chip, supporting data rates up to 120 kbps. The device operates from a single +5V power supply and includes internal charge pumps to generate the necessary positive and negative voltages for RS-232 signaling without requiring external components. It features ESD protection rated at ±15kV according to the Human Body Model and ±8kV according to the Contact Discharge Model. The unit is housed in a standard 16-pin DIP package.

Feature Summary

• Integrated dual drivers and receivers for complete RS-232 communication channels
• Internal charge pump circuitry eliminates the need for external capacitors
• Robust electrostatic discharge (ESD) protection for reliable operation
• Single +5V power supply operation simplifies system design

Applications

• Industrial control systems requiring serial communication
• Data acquisition equipment interfaces
• Point-of-sale (POS) terminals
• Medical instrumentation serial links

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas Electronics. Ensure the component matches the original Harris specifications or confirm if the current production version is the Renesas equivalent. Check for pin compatibility and electrical parameter alignment before procurement.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with minimal external bill of materials. It is suitable for designs needing high ESD immunity and operation from a standard 5V logic supply. Consider the 16-pin DIP package constraints for PCB layout and verify that the 120 kbps speed meets the application's throughput requirements.

Part Context

This component belongs to the family of RS-232 transceivers used for serial data transmission. It serves as an interface between microprocessors or DSPs operating at TTL/CMOS levels and RS-232 compatible devices. The dual configuration allows for handling two independent serial ports within a single integrated circuit.

Replacement Considerations

Direct replacements include the MAX205ACPE (Maxim Integrated) and the SP205E (Exar). These parts share similar pinouts and electrical characteristics. Verify that the replacement part supports the same voltage range and ESD protection levels.
