HIN238CB-T

Overview

The HIN238CB-T is a quad driver and quad receiver RS-232 transceiver manufactured by Harris Corporation, part of the HIN238 series. It operates on a single +5 V power supply and supports data rates up to 120 kbps. The device features four drivers and four receivers for full-duplex communication. It utilizes external capacitors for charge pump functionality. The component is housed in a 24-pin SOIC package and is designed for surface mount installation. It functions as an interface between microprocessors and RS-232 compliant equipment.

Feature Summary

• Provides four independent drivers and four independent receivers for simultaneous bidirectional data transmission.
• Operates from a single +5 V power supply using internal charge pumps to generate required voltage levels.
• Designed for low power consumption with shutdown mode capabilities to minimize current drain.

Applications

• Industrial control systems requiring serial communication interfaces.
• Modem connections and portable instruments.
• RS-232 compliant data transmission links in embedded systems.

Procurement Notes

Verify the manufacturer status carefully, as Harris Semiconductor was acquired by Intersil, which was subsequently acquired by Renesas Electronics. Confirm whether the specific suffix 'T' indicates tape and reel packaging or other handling variations. Ensure the source document explicitly identifies Harris Corporation as the original manufacturer for this specific part number variant.

Selection Notes

Select this component when a quad driver/receiver configuration is required for RS-232 applications. Compare against the HIN238CPZ for through-hole alternatives or HIN238IBZ for industrial temperature ranges. Verify that the 120 kbps data rate meets system requirements and that the SOIC-24 package fits the PCB layout constraints.

Part Context

The HIN238CB-T belongs to the HIN238 family of RS-232 transceivers originally developed by Harris Semiconductor. This family is characterized by its ability to operate from a single 5 V supply while providing EIA/TIA-232-E compatible signal levels. The CB suffix typically denotes commercial temperature range operation in a specific package style.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider checking datasheets for equivalent parts from Renesas or Intersil, such as the HIN238CN or MAX238, ensuring pin compatibility and electrical specifications match.
