HIN241IB

Overview

The HIN241IB is a high-speed, low-power RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates from a single 3.3V supply and features fail-safe circuitry to ensure the receiver output defaults to a logic high state when inputs are open or disconnected. The device supports data rates up to 20 Mbps and includes thermal shutdown protection for enhanced reliability. It is housed in an 8-pin SOIC package.

Feature Summary

• Fail-safe receiver design ensures a high logic level at the receiver output during input disconnection
• Integrated thermal shutdown protection prevents damage during excessive power dissipation
• Low-power operation optimized for battery-powered applications with a single 3.3V supply
• High-speed data transmission capability supporting rates up to 20 Mbps

Applications

• Industrial automation systems requiring robust RS-485 communication
• Building automation and control networks
• Metering equipment with serial data interfaces
• Point-of-sale (POS) terminals and payment systems

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range and 'B' denotes the 8-pin SOIC package variant. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure pinout compatibility with existing PCB layouts designed for standard RS-485 transceivers.

Selection Notes

Select this component for designs requiring reliable half-duplex communication in noisy environments. The fail-safe feature is critical for maintaining system stability during bus faults. Consider the 20 Mbps speed limit when evaluating higher-bandwidth requirements. Verify that the 3.3V supply voltage aligns with the target system's power architecture.

Part Context

This transceiver belongs to the Renesas RS-485/RS-422 interface family, providing differential signaling for long-distance communication. It complements other serial interface solutions by offering a balance of speed, power efficiency, and fault protection suitable for embedded industrial and commercial applications.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX3485 or SN75LBC184 if sourcing constraints exist. Ensure substitute devices match the 3.3V operating voltage and support the required 20 Mbps data rate. Verify that replacement parts also include fail-safe and thermal shutdown features for equivalent system protection.
