HIN232ACP

Overview

The HIN232ACP 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 with onboard charge pump voltage converters generating +10V and -10V supplies. The device features two drivers and two receivers in a 16-pin SSOP package. Key electrical parameters include a data rate of 230 kbit/s, typical power consumption of 5 mA, and an output swing of ±10V. Receivers offer ±30V input voltage range, 3kΩ to 7kΩ input impedance, and 0.5V hysteresis for noise rejection.

Feature Summary

• Onboard charge pump voltage converters generate required positive and negative supplies from a single +5V source
• High data rate capability up to 230 kbit/s suitable for ISDN and high-speed modem applications
• Receiver inputs feature hysteresis to significantly improve noise rejection performance
• Drivers provide true TTL/CMOS input compatibility with slew rate-limited outputs

Applications

• Portable computer systems requiring high-speed serial communication
• Peripheral connections such as printers and terminals
• Instrumentation and UPS systems needing reliable RS-232 links
• Modem interfaces in environments without ±12V power availability

Procurement Notes

Verify the specific suffix 'ACP' against official Harris or Intersil documentation to confirm exact package type and temperature rating. Ensure RoHS compliance status matches project requirements, noting that Pb-Free Plus Anneal versions are available. Confirm pinout compatibility if replacing legacy components. Check for active status as older Harris products may have transitioned to Renesas Intersil lines.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are absent. The HIN232ACP is appropriate for designs requiring 230 kbit/s speeds with low power consumption around 5 mA. Consider the SSOP package constraints for PCB layout. Verify that the ±30V receiver input tolerance and noise immunity meet the specific environmental conditions of the target application.

Part Context

The HIN232A belongs to the Harris RS-232 transceiver family designed for high-speed operation without dual voltage supplies. This series includes variants like HIN202E and HIN232E, often featuring enhanced ESD protection. The ACP designation typically indicates a specific plastic surface-mount package variant within the broader HIN232A product line offered by Harris and later Intersil/Renesas.

Replacement Considerations

Public confirmed substitutes include the ADM232A from Analog Devices and the MAX232 from Maxim Integrated. These devices share similar functional characteristics and pinouts. Verify that replacement parts support the same 230 kbit/s data rate and single +5V operation before integration.
