HIN239CP

Overview

The Intersil HIN239CP is a high-speed RS-232 transceiver designed for single +5V power supply operation. It integrates onboard voltage doubler and inverter circuits to generate the required ±10V logic levels from the single supply, eliminating the need for external dual-voltage sources. The device features four drivers and four receivers, supporting data rates up to 120kbps. It utilizes a 24-pin PDIP package with through-hole mounting. The component operates within a temperature range of 0°C to +70°C and meets EIA RS-232E and V.28 specifications.

Feature Summary

• Integrates charge pump circuitry to generate internal ±10V supplies from a single +5V source
• Provides full RS-232 compliance with four drivers and four receivers
• Features receiver hysteresis to enhance noise immunity
• Maintains low power consumption during active operation

Applications

• High-speed serial communication ports in computer systems
• Portable and laptop computer interfaces
• Peripheral connections such as printers and terminals
• Instrumentation and UPS control links

Procurement Notes

Verify the specific suffix 'CP' against current manufacturer documentation to confirm pinout compatibility and RoHS status. Confirm availability as this part number may be superseded by newer revisions or alternative packages. Ensure the procurement channel provides original manufacturer packaging to prevent counterfeit components.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required. It is suitable for applications needing four transmit and receive channels. Consider the PDIP package constraints for PCB layout. Verify that the 120kbps speed meets system requirements compared to higher-speed alternatives like the HIN232A.

Part Context

The HIN239 series belongs to Intersil's family of high-speed RS-232 transceivers. These devices are engineered to replace traditional dual-supply solutions. The HIN239CP specifically denotes the PDIP package variant. This family simplifies design by integrating charge pumps, reducing external component count and board space.

Replacement Considerations

Direct substitutes include the MAX239CWG+ from Analog Devices/Maxim Integrated. Verify pin-to-pin compatibility and electrical characteristics before substitution. Check for updated package options if surface mount is preferred.
