HIN238CPZ

Overview

The Intersil HIN238CPZ is a quad RS-232 transceiver designed for single-supply operation. It integrates four drivers and four receivers to support full-duplex communication at data rates up to 120 kbps. The device operates within a supply voltage range of 4.5 V to 5.5 V and draws a typical operating current of 15 mA. Packaged in a 24-pin PDIP format, it is suitable for through-hole mounting. The component supports an industrial temperature range with a minimum operating temperature of 0°C and a maximum of +70°C.

Feature Summary

• Integrates four independent drivers and four receivers for comprehensive RS-232 signal conversion
• Enables full-duplex data transmission over standard serial communication interfaces
• Operates from a single 5 V power supply without requiring external negative voltage generation

Applications

• Industrial control systems requiring robust serial communication links
• Data acquisition equipment utilizing multiple RS-232 ports
• Embedded systems needing reliable half or full duplex connectivity

Procurement Notes

Verify the specific package variant and manufacturer origin before procurement, as Renesas Electronics acquired Intersil's semiconductor assets. Confirm that the 24-pin PDIP form factor matches the target PCB footprint requirements. Ensure the component meets RoHS compliance standards if required by the end product regulations. Check for any obsolescence notices or lifecycle status updates from the current supplier.

Selection Notes

Select this component when a design requires four independent RS-232 channels on a single integrated circuit. It is appropriate for applications where space constraints favor a 24-pin package over discrete solutions. Consider the 120 kbps speed limit when evaluating compatibility with high-speed serial protocols. Verify that the 0°C to +70°C operating range aligns with the environmental conditions of the intended deployment site.

Part Context

The HIN238 belongs to the HIN23x series of RS-232 transceivers manufactured by Intersil, now part of Renesas Electronics. This series provides low-power, single-supply solutions for serial communication. The CPZ suffix typically denotes a commercial temperature grade and a plastic dual in-line package. It serves as a bridge between microprocessor logic levels and RS-232 voltage standards.
