HIN239CPZ

Overview

The HIN239CPZ is a full RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for high-speed serial communication. It integrates three drivers and five receivers within a single chip, supporting data rates up to 120Kbps. The device operates on a single +5V power supply, utilizing onboard voltage converters to generate the necessary positive and negative voltages for RS-232 signaling. It is housed in a 24-SOIC surface-mount package with a width of 7.50mm. The component functions reliably across an operating temperature range of 0°C to 70°C and features a receiver hysteresis of 500mV to enhance noise immunity.

Feature Summary

• Integrates three independent drivers and five receivers for comprehensive RS-232 connectivity
• Operates from a single +5V supply using internal charge pump circuitry
• Includes 500mV receiver hysteresis to improve signal integrity in noisy environments

Applications

• Industrial control systems requiring robust serial communication
• Computer peripheral interfaces such as printers and terminals
• Instrumentation and measurement equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices, as this part may be discontinued. Ensure the specific suffix matches the required package type and temperature rating before ordering.

Selection Notes

Select this component when a single-supply RS-232 solution with multiple driver and receiver channels is required. Compare against similar parts like the HIN238 or MAX239 based on pin compatibility and data rate requirements. Verify that the 24-SOIC package fits the target PCB layout constraints.

Part Context

This component belongs to the HIN23x series of high-speed RS-232 transceivers. These devices are engineered to replace traditional dual-supply solutions, simplifying power design in portable and battery-operated systems. The series offers various configurations of drivers and receivers to suit different interface needs.
