HIN207ECB-T

Overview

The HIN207ECB-T is an RS-232 transceiver integrated circuit manufactured by Intersil, now part of Renesas Electronics. It operates on a single +5V power supply and features one driver and three receivers. The device supports data rates up to 230 kb/s and includes onboard charge pumps to generate the necessary ±10V supplies from the 5V input. It provides ±15kV ESD protection on I/O pins and meets EIA/TIA-232 specifications. The component is housed in a 24-pin SOIC package and is rated for commercial operating temperatures ranging from 0°C to +70°C.

Feature Summary

• Integrated charge pump voltage converters eliminate the need for external dual-voltage power supplies.
• High electrostatic discharge (ESD) protection capability on RS-232 input and output pins.
• Single +5V power supply operation simplifies system design and reduces component count.
• True TTL/CMOS input compatibility ensures direct interfacing with standard logic families.

Applications

• ISDN terminal adaptors requiring high-speed serial communication.
• Portable computers and notebook systems utilizing RS-232 peripherals.
• Industrial instrumentation and control equipment interfaces.
• Modem applications supporting data rates up to 230 kbps.

Procurement Notes

Verify current availability status as this specific part number may be discontinued or superseded by newer revisions within the HIN207 family. Confirm that the CB suffix corresponds to the required commercial temperature range and SOIC-24 package configuration. Cross-reference with official Renesas documentation to ensure compliance with updated RoHS directives and lead-free manufacturing standards before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring a single-supply RS-232 interface with moderate speed capabilities. Ensure the application environment remains within the 0°C to +70°C commercial temperature range. Verify that the 230 kb/s data rate suffices for the target protocol. Consider alternative industrial-grade variants if extended temperature ranges are required for harsher operational conditions.

Part Context

This device belongs to the HIN207 series of RS-232 transceivers designed for low-power, single-supply applications. The series is characterized by its ability to operate without external ±12V rails, making it suitable for modern digital systems powered exclusively by 5V or 3.3V sources. The HIN207ECB-T specifically denotes the commercial grade variant with enhanced ESD protection features compared to earlier generations.

Replacement Considerations

The ICL3217E is documented as a lower power replacement option within the same manufacturer portfolio. Verify pinout compatibility and electrical parameter alignment before substitution. Check for any functional differences in shutdown modes or capacitor requirements between the legacy HIN207 and potential successor devices.
