HIN232ECA

Overview

The HIN232ECA is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Harris Corporation. It meets EIA-232-E and V.28 specifications, operating on a single +5V power supply with onboard charge pump converters generating ±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, an output swing of ±10V, and input voltage tolerance up to ±30V. It operates within a temperature range of 0°C to +70°C.

Feature Summary

• Onboard charge pump voltage converters generate required positive and negative supplies from a single +5V source
• High-speed data transmission capability suitable for ISDN and modem applications
• Integrated hysteresis on receivers to significantly improve noise rejection performance

Applications

• Portable computers and laptop systems requiring high-speed serial communication
• Peripheral connections including printers and terminals
• Instrumentation and uninterruptible power supply (UPS) control interfaces

Procurement Notes

Verify the specific suffix 'E' against official Harris or Renesas documentation to confirm the commercial temperature grade and RoHS compliance status. Ensure the ordering part number matches the exact package type and lead finish requirements for your manufacturing process. Cross-reference with current manufacturer datasheets as product lines may have been transferred or updated.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are absent. It is appropriate for designs requiring 230 kbit/s throughput with TTL/CMOS compatible inputs. Consider the 16-pin SSOP footprint constraints and verify that the 0.1µF external capacitor requirement fits the board layout. Check if the non-shutdown variant meets the system's power management needs.

Part Context

This device belongs to the HIN232 family of RS-232 transceivers originally developed by Harris Semiconductor, later acquired by Intersil and subsequently Renesas Electronics. The family provides various driver/receiver combinations for standard serial communication protocols. The HIN232 specifically offers a balanced configuration of two drivers and two receivers.

Replacement Considerations

HIN232ACBNZ is a confirmed RoHS-compliant replacement variant within the same family offering identical functionality.
