HIN232CPZ

Overview

The HIN232CPZ is a high-speed RS-232 transceiver manufactured by Renesas Electronics, formerly Intersil. It operates on a single +5V power supply and meets EIA RS-232E and V.28 specifications. The device features two drivers and two receivers in a 16-pin PDIP package. It supports data rates up to 120 kbps with an operating temperature range of 0°C to +70°C. Internal charge pumps generate the required ±10V supplies using only 0.1µF external capacitors.

Feature Summary

• Single-supply operation eliminates the need for external ±12V rails via onboard voltage conversion
• Integrated ESD protection safeguards transmitter outputs and receiver inputs against electrostatic discharge events
• Receiver hysteresis enhances noise rejection capabilities for reliable signal integrity
• TTL/CMOS input compatibility ensures seamless integration with standard logic families

Applications

• High-speed RS-232 communications ports in computer systems
• Portable and mainframe computer peripheral connections
• Printers and terminals requiring serial interface connectivity
• Instrumentation and UPS systems utilizing RS-232 control lines

Procurement Notes

Verify the specific suffix CPZ corresponds to the PDIP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the component matches the original Intersil design specifications now managed under the Renesas portfolio. Cross-reference pinouts carefully as package variations exist within the HIN232 family.

Selection Notes

Select this component for applications requiring dual driver and receiver configurations without ±12V availability. Compare against HIN232ACBNZ if surface-mount packaging is preferred over through-hole DIP. Consider the HIN232E series if enhanced ±15kV ESD protection is required for harsh environments. Verify that the 120 kbps data rate suffices for the target application speed requirements.

Part Context

This part belongs to the HIN232 family of RS-232 transceivers originally developed by Intersil and acquired by Renesas. The family shares common architecture but varies in driver/receiver counts and ESD protection levels. The HIN232 specifically provides a balanced 2-transmitter, 2-receiver configuration suitable for general-purpose serial communication interfaces.

Replacement Considerations

HIN232ACBNZ offers identical electrical performance in a surface-mount SOIC package. HIN232E variants provide upgraded ±15kV ESD protection while maintaining similar functionality. Verify pin compatibility before substituting, as package dimensions differ significantly between PDIP and SOIC formats.
