HIN238IBZ-T

Overview

The HIN238IBZ-T is a RS-232 interface integrated circuit manufactured by Renesas Electronics. It functions as a full-duplex transceiver featuring four drivers and four receivers. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum rating of 5.5 V. It supports data rates up to 120 kb/s and draws a typical operating supply current of 15 mA. Designed for surface mount applications, it is housed in a SOIC-24 package. The component requires external capacitors for operation and is characterized for industrial temperature ranges.

Feature Summary

• Provides full-duplex communication capability through four independent drivers and four receivers
• Designed for reliable serial data transmission at speeds up to 120 kb/s
• Operates on a single 5 V power supply with low quiescent current consumption
• Includes internal protection mechanisms to safeguard against damage from high-voltage inputs

Applications

• Industrial control systems requiring robust serial communication
• Modem interfaces and portable instruments
• RS-232 data transmission in commercial equipment

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status via the manufacturer's datasheet. Check product lifecycle status as older Intersil/Renesas parts may be subject to discontinuation or limited availability. Ensure the SOIC-24 package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring four-channel RS-232 connectivity without the need for multiple discrete transceivers. Verify that the system power supply remains stable between 4.5 V and 5.5 V. Consider the 15 mA supply current impact on overall system power budget. Ensure external coupling capacitors are selected according to the datasheet specifications to maintain signal integrity at the target baud rate.

Part Context

This part belongs to the HIN238 series of RS-232 transceivers. It is functionally similar to other industry-standard quad RS-232 drivers but is branded under Renesas Electronics following their acquisition of Intersil. The 'IBZ' designation typically refers to the specific package type and temperature grade, while '-T' denotes the tape and reel shipping format.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Renesas cross-reference tools or datasheets for compatible alternatives such as the MAX238 or SP3238 families, ensuring pin compatibility and electrical specifications match.
