HIN232ECBN

Overview

The HIN232ECBN is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Harris Corporation. It meets EIA-232E and V.28 specifications, operating on a single +5V power supply via onboard charge pump voltage converters that generate +10V and -10V supplies. The device features two drivers and two receivers with true TTL/CMOS input compatibility. Key electrical parameters include a data rate of 230kbit/s, ±10V output swing, and a typical power consumption of 5mA. It operates within a temperature range of 0°C to +70°C and utilizes a 16-pin SOICN package.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external ±12V supplies
• High data rate capability up to 230kbit/s for fast communication
• TTL/CMOS compatible inputs with slew-rate limited outputs
• Receivers feature hysteresis to improve noise rejection

Applications

• Portable computers and laptops requiring compact serial interfaces
• Printers and terminals connected via RS-232 ports
• Instrumentation systems and UPS units needing reliable serial communication

Procurement Notes

Verify the specific suffix 'CBNZ' or 'CBN' against current manufacturer documentation to confirm RoHS compliance and lead-free status. Ensure the ordering code matches the exact package type and temperature grade required for the design. Cross-reference with Renesas Electronics, the successor to Harris Semiconductor, for updated lifecycle and availability information.

Selection Notes

Select this component when a single +5V supply is available but RS-232 levels are required without external negative voltage generators. It is suitable for applications demanding high data rates up to 230kbit/s. Consider the 16-pin SOIC package constraints and the 0°C to +70°C commercial temperature range during board layout and thermal design.

Part Context

The HIN232 series belongs to the family of high-speed RS-232 transceivers originally developed by Harris Semiconductor. These devices were designed to simplify RS-232 interface design by integrating charge pumps. Harris Corporation's semiconductor division was later acquired by Intersil, which subsequently merged with Renesas Electronics, making Renesas the current steward of this product line.

Replacement Considerations

Direct replacements include the HIN232ACBNZ and HIN232ECBNZ from Renesas Electronics. Verify pinout compatibility and ensure the substitute part supports the same 230kbit/s data rate and +5V single-supply operation.
