HIN232ECB

Overview

The HIN232ECB is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Harris Corporation. It meets EIA RS-232E and V.28 specifications, designed for systems lacking ±12V supplies. The device operates on a single +5V power supply using onboard charge pumps to generate internal voltages. It features two drivers and two receivers with TTL/CMOS compatibility. Key electrical parameters include a data rate of 230 kbit/s, ±10V output swing, and ±30V input voltage range. The package is SSOP-16, operating within a temperature range of 0°C to +70°C.

Feature Summary

• Integrated onboard charge pump eliminates need for external dual-voltage supplies
• High-speed operation suitable for ISDN and modem applications
• Robust ESD protection on RS-232 I/O pins

Applications

• Portable computers and laptops requiring serial communication
• Printers and terminals in peripheral systems
• Instrumentation and UPS monitoring interfaces

Procurement Notes

Verify the specific suffix 'CB' against official Harris or successor manufacturer datasheets to confirm pinout and package dimensions. Ensure compliance requirements match the original non-RoHS status if applicable. Confirm thermal characteristics align with the intended enclosure design before finalizing procurement orders.

Selection Notes

Select this component when a single +5V supply is available but RS-232 levels are required. It serves as a direct replacement for older dual-supply transceivers. Verify that the 230 kbit/s speed meets system timing requirements. Check if the SSOP-16 footprint matches the existing PCB layout constraints.

Part Context

This part belongs to the HIN232 family of RS-232 transceivers originally developed by Harris Corporation. The technology was later transferred to Intersil and subsequently Renesas Electronics. The HIN232 series is widely recognized for enabling RS-232 communication in low-voltage digital systems without complex power management circuits.

Replacement Considerations

HIN232ECBNZ-T (Intersil/Renesas) offers RoHS compliance with identical functionality. SP3245ECY-L provides higher speed but different pin counts. MAX3232 is a common alternative requiring similar capacitor configurations.
