HIN232CP

Overview

The Intersil HIN232CP is a dual transmitter and receiver RS-232 line transceiver designed for single +5V power supply operation. It utilizes onboard charge pump voltage converters to generate the required ±10V supplies from the 5V input, eliminating the need for external dual-voltage sources. The device supports data rates up to 120kbps and features true TTL/CMOS input compatibility. It includes two drivers and two receivers with ±30V input voltage ranges and hysteresis for improved noise rejection. Packaged in a 16-pin PDIP format, it operates within a temperature range of 0°C to +70°C.

Feature Summary

• Single +5V power supply operation with integrated onboard voltage doubler and inverter
• High-speed data transmission capability supporting rates up to 120kbps
• Enhanced noise rejection through receiver input hysteresis and ±30V input tolerance

Applications

• Portable computers and laptop systems requiring high-speed serial communication
• Industrial instrumentation and control equipment
• Uninterruptible Power Supply (UPS) monitoring interfaces

Procurement Notes

Verify the specific suffix 'CP' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure that the ordering information matches the exact pinout and electrical specifications required for the target design, as suffixes may indicate variations in packaging or environmental ratings.

Selection Notes

Select this component when a single +5V supply is available and dual RS-232 channels are required. It is suitable for applications needing moderate data rates up to 120kbps. Consider alternative models if higher data rates or ESD protection levels are necessary, as this specific part focuses on basic high-speed performance without advanced protection features.

Part Context

The HIN232CP belongs to the Intersil HIN232 family of high-speed RS-232 transceivers. This family is characterized by its ability to operate from a single 5V supply while meeting EIA/TIA-232-E standards. The CP variant specifically denotes the plastic dual in-line package configuration, distinguishing it from surface-mount options like the CBZ or CNZ variants.

Replacement Considerations

Direct replacements include the HIN232ACBNZ for surface mount applications or other HIN232 family members with compatible pinouts. Verify that substitute parts maintain the same 120kbps data rate and single-supply architecture to ensure functional equivalence in existing designs.
