HIN238IP

Overview

The HIN238IP is a low-power, dual RS-232 transceiver manufactured by Harris Corporation. It operates from a single +5V supply and integrates charge pump circuitry to generate the necessary positive and negative voltages for RS-232 signal levels without requiring external components. The device features receive inputs that are tolerant to ±30V overvoltage protection. It supports data rates up to 120 kbps and includes logic-compatible input thresholds for direct interfacing with microprocessors and DSPs.

Feature Summary

• Integrates dual charge pumps to eliminate the need for external capacitors in voltage generation
• Provides robust ±30V overvoltage tolerance on all receive inputs
• Supports direct interface with standard TTL or CMOS logic families
• Operates efficiently from a single +5V power supply

Applications

• Industrial control systems requiring isolated serial communication
• Data acquisition modules connecting to PC-based monitoring stations
• Embedded systems utilizing microcontrollers for RS-232 connectivity

Procurement Notes

Verify the manufacturer source carefully as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently by Renesas Electronics. Confirm the specific date code and lot traceability requirements for your application. Ensure the component meets current environmental compliance standards relevant to your region before finalizing procurement.

Selection Notes

Select this component when a compact, low-pin-count solution is needed for dual-channel RS-232 communication. It is suitable for designs where board space is limited and external voltage generation components must be avoided. Consider the 120 kbps speed limit when designing for high-throughput applications.

Part Context

This component belongs to the family of standard RS-232 transceivers designed for reliable serial communication in embedded environments. It serves as a bridge between logic-level digital signals and the higher voltage swings required by the RS-232 standard, facilitating interoperability between computers and peripheral devices.
