HIN239CBZ-T

Overview

The HIN239CBZ-T is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in a 24-SOIC surface-mount package. It integrates three drivers and five receivers to support complex serial communication interfaces. The device operates on a single +5V power supply, utilizing onboard charge pumps to generate the necessary positive and negative voltages for RS-232 signaling without external high-voltage sources. It supports data rates up to 120Kbps and functions within an industrial temperature range of 0°C to 70°C. The component meets RoHS3 standards and carries an MSL rating of 3.

Feature Summary

• Integrates three independent drivers and five receivers for comprehensive RS-232 connectivity
• Utilizes onboard voltage conversion circuitry to operate from a single +5V supply
• Features receiver hysteresis to enhance noise immunity in electrically noisy environments

Applications

• Industrial control systems requiring multiple serial ports
• Communication modules with mixed driver and receiver counts
• Embedded devices operating on standard 5V logic levels

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube, as availability varies. Confirm current manufacturing status, as related HIN239 variants may be obsolete or subject to product change notices. Ensure the supplier provides valid traceability documentation for this specific Renesas part number before finalizing acquisition.

Selection Notes

Select this component when a design requires exactly three transmit and five receive channels within a single IC. It is suitable for applications where space constraints prevent using multiple discrete transceivers. Verify that the required data rate does not exceed 120Kbps and that the system environment remains within the specified commercial/industrial temperature limits.

Part Context

This part belongs to the HIN239 family of high-speed RS-232 transceivers. It shares functional similarities with other members like the HIN239CBZ but differs in packaging format due to the reel designation. The family is designed for systems needing robust serial communication without the complexity of external charge pump capacitors beyond the minimum required values.

Replacement Considerations

Public confirmed substitute part numbers include MAX239CWG+T from Analog Devices Inc./Maxim Integrated. Verify pin compatibility and electrical specifications before substitution.
