HIN239CBZ

Overview

The HIN239CBZ 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 supply utilizing onboard voltage doublers and inverters to generate the required ±10V levels for RS-232 signaling. It supports data rates up to 120Kbps with a receiver hysteresis of 500mV to enhance noise immunity. The component functions within a commercial temperature range of 0°C to 70°C and complies with RoHS3 standards.

Feature Summary

• Integrates multiple driver and receiver channels within a single compact package
• Generates internal high-voltage supplies from a single low-voltage source
• Includes input hysteresis to improve signal integrity in noisy environments

Applications

• Industrial control systems requiring robust serial communication
• Portable computing devices and laptop peripherals
• Test and measurement instrumentation

Procurement Notes

Verify current availability status as this component has been officially declared obsolete by the manufacturer. Confirm that any substitute parts maintain identical pin configurations and electrical specifications to ensure compatibility with existing designs without requiring circuit modifications.

Selection Notes

Select this component when designing systems requiring multiple independent RS-232 channels within a limited board area. Ensure the application environment remains within the specified commercial temperature limits. Verify that the power supply architecture can accommodate the charge pump requirements for generating negative voltages.

Part Context

This part belongs to the HIN23x series of high-speed RS-232 transceivers designed for single-supply operation. The series provides various channel configurations to suit different interface needs while maintaining compatibility with TTL and CMOS logic levels. These components are engineered to replace traditional dual-supply solutions in modern electronic systems.
