HIN202ECP

Overview

The Intersil HIN202ECP is a high-speed RS-232 transceiver designed for single +5V power supply operation. It integrates onboard charge pump voltage converters to generate the necessary positive and negative supplies from the 5V input, eliminating the need for external ±12V rails. The device features two drivers and two receivers, supporting full-duplex communication at data rates up to 230 kb/s. It meets EIA high-speed RS-232E and V.28 specifications. Key electrical parameters include a maximum supply voltage of 5.5 V, a minimum of 4.5 V, and an operating supply current of 15 mA. The component offers ±15 kV ESD protection on I/O pins and operates within temperature ranges of -40°C to +85°C or 0°C to +70°C depending on the specific grade.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage converters generating internal ±10V supplies
• High-speed data transmission capability up to 230 kb/s suitable for ISDN and high-speed modem applications
• Robust electrostatic discharge (ESD) protection rated at ±15 kV on transmitter outputs and receiver inputs
• TTL/CMOS compatible inputs with slew-rate-limited outputs and hysteresis-enhanced receivers for improved noise rejection

Applications

• Portable computers, mainframes, and laptops requiring high-speed RS-232 communications ports
• Peripheral devices such as printers and terminals
• Instrumentation systems and uninterruptible power supplies (UPS)
• Modems and ISDN terminal adaptors

Procurement Notes

Verify the exact suffix configuration against official Renesas or Intersil documentation to confirm temperature range and package variant. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm moisture sensitivity level and reflow soldering profiles during procurement planning.

Selection Notes

Select this component when designing systems limited to a single +5V power source without access to dual polarity supplies. It is appropriate for applications requiring moderate data rates up to 230 kb/s with robust ESD protection. Consider alternative models if lower power consumption in shutdown mode is required, as the basic HIN202E lacks a dedicated low-power shutdown feature found in other family members like the HIN211E.

Part Context

The HIN202ECP belongs to the HIN202E family of RS-232 transmitters and receivers manufactured by Intersil, now part of Renesas Electronics. This family was designed to replace older RS-232 chips that required complex external charge pumps and multiple voltage rails. The HIN202 variant specifically provides two drivers and two receivers, making it a standard choice for general-purpose serial communication interfaces in industrial and commercial equipment.

Replacement Considerations

Direct replacements within the same family include the HIN202ECBNZ and HIN202EIBZ, which offer similar functionality but may differ in packaging (SOIC-Narrow vs SOIC-Wide) or temperature rating. Verify pinout compatibility and electrical specifications when substituting.
