HIN230IB

Overview

The HIN230IBN is a single transmitter and receiver RS-232 interface circuit from the Harris Corporation HIN200-HIN213 family. It meets EIA RS-232E and V.28 specifications, utilizing an onboard charge pump to generate +10V and -10V supplies from a single +5V power source. The device features three-state TTL/CMOS compatible outputs with ±10V output swing for +5V inputs. Key electrical parameters include a data rate of 120kbit/s, a maximum slew rate of 30V/µs, and an input voltage range of ±30V. Typical supply current is 5mA, reducing to 1µA in shutdown mode.

Feature Summary

• Onboard voltage doubler and inverter eliminates need for external dual supplies
• TTL/CMOS compatible inputs and outputs ensure broad logic integration
• Low power consumption with dedicated shutdown function for energy efficiency
• Input protection up to ±30V with hysteresis for improved noise rejection

Applications

• Computer serial communication ports
• Portable and laptop computer interfaces
• Peripheral connections such as printers and terminals

Procurement Notes

Verify the complete part number suffix, typically 'N' for plastic DIP or 'P' for SOIC, against the manufacturer's official datasheet to confirm package type and temperature rating. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Cross-reference the manufacturer designation, which may appear under Intersil or Renesas following corporate acquisitions, to align procurement records with current product line ownership.

Selection Notes

Select this component when designing systems requiring RS-232 connectivity with only a +5V supply available. It is suitable for space-constrained designs due to minimal external capacitor requirements compared to older generations. Verify that the 120kbit/s data rate meets application timing needs. Consider the HIN203 or HIN205 if zero external capacitors are strictly required, or the HIN213 if multiple receivers are needed in shutdown mode.

Part Context

This device belongs to the HIN200-HIN213 family of RS-232 transceivers originally developed by Harris Semiconductor. The family provides various combinations of drivers and receivers to suit different interface complexities. These components were widely adopted before the prevalence of lower-voltage standards, serving as a bridge between TTL/CMOS logic and legacy RS-232 equipment.

Replacement Considerations

Publicly confirmed direct substitutes include the MAX232 and MAX233 from Maxim Integrated (now Analog Devices), as well as the SP3232 from MaxLinear. These alternatives offer similar functionality, single-supply operation, and RS-232 compliance. Verify pinout compatibility and package dimensions before substitution to ensure board-level interchangeability.
