HIN238IB

Overview

The HIN238IB is a dual RS-232 transceiver manufactured by Harris Corporation, designed for low-power applications. It operates from a single +5V supply and incorporates internal charge pumps to generate the necessary positive and negative voltages for RS-232 communication. The device features two drivers and two receivers, providing full compliance with EIA/TIA-232-E standards. It includes protection circuitry on both input and output pins to safeguard against electrostatic discharge and other transient events. The IB suffix indicates an industrial temperature range specification, ensuring reliable operation in demanding environments.

Feature Summary

• Dual driver and receiver configuration for simultaneous bidirectional communication
• Internal charge pump eliminates external capacitors for voltage generation
• Single +5V power supply operation reduces system complexity
• Integrated protection circuits enhance reliability against electrical stress

Applications

• Industrial control systems requiring robust serial communication
• Portable battery-powered equipment due to low power consumption
• Embedded systems interfacing with RS-232 peripherals
• Telecommunications equipment operating in industrial environments

Procurement Notes

Verify the specific manufacturer documentation for the HIN238IB to confirm current availability and exact specifications. Ensure that the procurement source provides authentic components with traceable origins. Check for any updated revisions or alternative part numbers that may have superseded this model. Confirm compatibility with existing system requirements before placing orders.

Selection Notes

Select the HIN238IB when a dual-channel RS-232 interface is required with minimal external component count. Its single-supply operation simplifies power design compared to older dual-supply alternatives. Consider its industrial temperature rating if the application environment experiences significant thermal variations. Evaluate the integrated protection features as a benefit for systems exposed to harsh electrical conditions.

Part Context

Harris Corporation was known for producing high-performance electronic components, including data converters and communication interfaces. The HIN series represents their line of interface products, with the HIN238IB being a specific variant tailored for dual RS-232 applications. This component fits within the broader category of standard RS-232 transceivers used in various computing and industrial sectors.

Replacement Considerations
