HIN207ECA-T

Overview

The HIN207ECA-T is an RS-232 transceiver integrated circuit manufactured by Intersil, now part of Renesas Electronics. It features one driver and three receivers, supporting data rates up to 230 kb/s. The device operates on a single +5V power supply with a range of 4.75 V to 5.25 V and consumes 20 mA of operating current. It provides ±15 kV ESD protection on I/O pins and functions within a commercial temperature range of 0°C to +70°C. The component is housed in a 24-pin SOIC package.

Feature Summary

• Integrated charge pump generates internal ±10V supplies from a single +5V source
• High electrostatic discharge protection rated at ±15kV for RS-232 I/O pins
• Compliant with EIA high-speed RS-232E and V.28 specifications

Applications

• ISDN terminal adaptors
• High-speed modem interfaces
• Computer peripheral connections

Procurement Notes

Verify the specific suffix 'CA' against official datasheets to confirm the commercial temperature grade (0°C to +70°C) versus industrial variants. Confirm RoHS compliance status as manufacturing sources may vary. Check for obsolescence or lifecycle changes since Intersil was acquired by Renesas. Ensure the SOIC-24 package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a single-driver, triple-receiver configuration is required for RS-232 communication. It is suitable for systems where ±12V supplies are unavailable, relying instead on onboard charge pumps. Choose this variant over industrial versions if the application environment remains within the 0°C to +70°C range. Verify that the 230 kb/s speed meets the system's baud rate requirements.

Part Context

This part belongs to the HIN207 family of RS-232 transceivers designed for high-speed applications like ISDN. The family shares common architecture but varies in driver/receiver counts and temperature grades. The HIN207 specifically offers a 1/3 configuration, distinguishing it from other members like the HIN206 or HIN208 which have different pinout configurations.

Replacement Considerations

The ICL3217E is documented as a low-power replacement option for the HIN207 series. Verify pin compatibility and electrical parameters before substitution.
