HIN231IP

Overview

The HIN231IP is a low-power, single-supply RS-232 transceiver manufactured by Harris Corporation. It integrates charge pump circuitry to generate the necessary positive and negative voltages from a single 5V supply, eliminating the need for external dual-voltage sources. The device features three drivers and five receivers, providing robust signal transmission with typical output voltages of +/-6V. It supports data rates up to 120 kbps and includes ESD protection on all pins. Packaged in a standard 20-pin DIP format, it is designed for reliable communication in industrial and commercial environments requiring serial data exchange.

Feature Summary

• Integrates internal charge pumps to derive dual supply voltages from a single 5V source
• Provides three independent drivers and five independent receivers for complex interface needs
• Includes electrostatic discharge (ESD) protection on all RS-232 lines

Applications

• Industrial control systems requiring serial communication
• Computer peripheral interfaces
• Modem connections

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the component matches the original Harris specifications or confirm if it is a Renesas-produced equivalent under the same part number. Check for pin compatibility and electrical parameter alignment with existing system designs before procurement.

Selection Notes

Select this component when a single 5V supply is available and multiple RS-232 channels are required. It is suitable for applications needing moderate data rates up to 120 kbps. Consider alternative parts if higher speed or lower power consumption is critical, or if the package type does not fit the PCB layout constraints.

Part Context

This component belongs to the family of RS-232 transceivers that simplify serial communication by integrating voltage conversion. Originally produced by Harris Semiconductor, these devices are widely used in legacy and modern industrial equipment. The IP suffix typically denotes an industrial temperature range and plastic DIP packaging, distinguishing it from commercial or ceramic variants.

Replacement Considerations

Renesas Electronics acquired Harris Semiconductor's analog and mixed-signal product lines. The HIN231IP may be produced by Renesas. Verify cross-reference compatibility with MAX232 or SP3232 series if pin-out and electrical characteristics must match exactly.
