HIN232IPZ

Overview

The HIN232IPZ is a high-speed, +5V powered RS-232 transmitter/receiver manufactured by Renesas Electronics Corporation. It meets EIA RS-232E and V.28 specifications, utilizing an onboard charge pump to generate ±10V supplies from a single +5V input. The device features two drivers and two receivers with true TTL/CMOS compatibility. Key electrical parameters include a data rate of 230 kbit/s, a supply voltage range of 4.5V to 5.5V, and a typical operating current of 5mA. It operates within a temperature range of 0°C to +70°C and utilizes a 16-pin PDIP package.

Feature Summary

• Onboard voltage doubler and inverter eliminate the need for external ±12V power supplies
• High data rate capability up to 230 kbit/s for fast communication
• Receivers feature hysteresis to significantly improve noise rejection
• Drivers provide 300Ω power-off source impedance for bus protection

Applications

• Portable computers, laptops, and mainframes requiring high-speed serial ports
• Peripheral connections including printers and terminals
• Instrumentation systems and Uninterruptible Power Supplies (UPS)
• Modems and ISDN terminal adaptors

Procurement Notes

Verify the specific suffix 'IPZ' against the manufacturer's official datasheet to confirm the package type and temperature grade. Ensure the ordering information matches the exact pinout and electrical characteristics required for the design. Cross-reference with Renesas documentation to confirm availability status and RoHS compliance details before finalizing procurement.

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 230 kbit/s speeds without external negative voltage generation. Compare with the HIN232E series if ±15kV ESD protection is necessary, as the standard HIN232 may lack this specific protection level. Verify that the 0°C to +70°C commercial temperature range meets the environmental requirements.

Part Context

The HIN232IPZ belongs to the Intersil/Renesas HIN232 family of RS-232 transceivers. This family is designed to replace traditional dual-supply interfaces by integrating charge pumps on-chip. The 'I' typically denotes the industrial or commercial temperature range variant, while 'PZ' indicates the lead-free PDIP package. It serves as a direct functional replacement for older MAX232-type devices in modern +5V systems.

Replacement Considerations

The HIN232ACBNZ is a documented alternative within the same high-speed family. Verify pin compatibility and ensure the replacement supports the required 230 kbit/s data rate. Check if the substitute offers the same 16-pin PDIP configuration.
