HIN238CBZ-T

Overview

The HIN238CBZ-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics, belonging to the HIN238 series. It integrates four drivers and four receivers in a single package, supporting data rates up to 120 kbps. The device operates on a single +5V power supply with onboard charge pumps generating ±10V for RS-232 signaling. Key electrical parameters include a maximum supply voltage of 5.5V, minimum of 4.5V, and typical operating current of 7mA. It features TTL/CMOS compatible inputs, ±30V receiver input tolerance, and 3kΩ to 7kΩ input impedance. The component is housed in a 24-pin SOIC-Wide package and supports surface-mount installation.

Feature Summary

• Integrates four independent drivers and four receivers for multi-port serial communication
• Utilizes onboard charge pump circuitry to generate required negative and positive voltages from a single 5V supply
• Provides enhanced noise rejection through receiver hysteresis and wide input voltage tolerance

Applications

• Portable computers and laptop systems requiring multiple serial ports
• Industrial instrumentation and control equipment
• Modems and peripheral interconnects

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Check for obsolescence notices as this part may be subject to lifecycle changes. Ensure packaging specifications match production line capabilities for SOIC-Wide 24 packages.

Selection Notes

Select this component when four independent RS-232 channels are required within a single integrated circuit. Compare against lower-channel-count alternatives like HIN202 or HIN207 if fewer ports suffice. Consider the 120 kbps speed limit for compatibility with legacy serial devices. Evaluate power consumption benefits of the single-supply architecture versus traditional dual-supply solutions.

Part Context

The HIN238CBZ-T is part of the HIN238 family of high-speed RS-232 transceivers designed for +5V operation. It succeeds earlier Intersil designs now under Renesas Electronics. The CBZ suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility with existing designs before considering alternative manufacturers.
