HIN202ACBN

Overview

The HIN202ACBN is a dual RS-232 transceiver manufactured by Renesas Electronics, originally part of the Intersil product line. It operates on a single 5V supply with a voltage range of 4.5V to 5.5V. The device features two drivers and two receivers, supporting full-duplex communication at data rates up to 120kbps or 230kbps depending on load conditions. Packaged in a 16-pin SOIC-Wide (0.295 inch / 7.50mm width) surface-mount format, it includes internal charge pumps for RS-232 voltage generation. The component offers 15kV ESD protection on I/O lines and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates external capacitors for standard RS-232 voltage levels
• High electrostatic discharge (ESD) protection rated at 15kV on input and output pins
• Low power consumption design suitable for battery-operated systems
• True driver performance ensures signal integrity over long cable distances

Applications

• Industrial control systems requiring robust serial communication
• Modem interfaces in telecommunications equipment
• Point-of-sale (POS) terminals and barcode scanners
• Medical instrumentation with serial data ports

Procurement Notes

Verify the manufacturer marking as Renesas Electronics, noting the historical Intersil lineage. Confirm the package type matches the 16-SOIC wide form factor. Ensure the suffix indicates the correct temperature grade and tape/reel configuration if applicable. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with high ESD tolerance. Compare against the HIN202EIBZ-T for higher speed variants or HIN202IBZ for tube packaging options. Consider the 120kbps vs 230kbps rate limits based on the specific capacitive load of the application. Verify that the 5V logic level matches the host microcontroller or processor interface requirements.

Part Context

This part belongs to the HIN202 family of RS-232 transceivers, which are widely used in legacy and industrial serial communication applications. The family includes variants like the HIN202E and HIN202C, differing primarily in speed ratings and packaging. The HIN202 series is known for its reliability and simplicity in converting TTL/CMOS levels to RS-232 signals without complex external circuitry.

Replacement Considerations

Direct substitutes include the MAX202EIDR from Texas Instruments and the SP202EEN from Maxim Integrated. These components share similar pinouts and electrical characteristics. Verify that the replacement supports the same 15kV ESD rating and operates within the required -40°C to +85°C temperature range.
