HIN207ECB

Overview

The HIN207ECB is an RS-232 transceiver integrated circuit manufactured by Intersil, part of the HIN207 series. It provides one driver and three receivers for single-ended signal transmission. The device operates on a single +5V supply with a maximum voltage of 5.25V and minimum of 4.75V, consuming 20mA of operating current. It supports data rates up to 230 kb/s and includes ±15kV ESD protection on I/O pins. The component is housed in a SOIC-24 package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates onboard charge pump converters to generate internal positive and negative voltages from a single +5V supply, eliminating the need for external dual supplies.
• Provides robust electrostatic discharge protection rated at ±15kV on transmitter outputs and receiver inputs to safeguard connected interfaces.
• Features true TTL/CMOS input compatibility and slew-rate-limited outputs to ensure signal integrity and reduce electromagnetic interference.

Applications

• High-speed RS-232 communications ports in computer systems
• Peripheral connections such as printers and terminals
• Instrumentation and uninterruptible power supply (UPS) interfaces

Procurement Notes

Verify the specific suffix against official documentation, as variations like ECbz or EIBz indicate differences in temperature ratings or packaging. Confirm RoHS compliance status and moisture sensitivity levels before integration. Check for end-of-life notifications or obsolescence notices from Renesas Electronics, as this component may be discontinued.

Selection Notes

Select this component when a single +5V supply is available and high-speed data transfer up to 230 kb/s is required. Ensure the application environment stays within the 0°C to +70°C commercial temperature range. Consider the SOIC-24 package dimensions for PCB layout constraints and verify that the 20mA quiescent current fits the system power budget.

Part Context

The HIN207ECB belongs to the HIN207E family of RS-232 transmitters and receivers designed to meet EIA/TIA-232 specifications. This family allows interface circuits to operate without ±12V supplies by using internal charge pumps. The device is part of a broader portfolio including variants with different driver/receiver counts and shutdown modes.

Replacement Considerations

Publicly confirmed substitutes include the ICL3217E, which offers similar functionality with lower power consumption and 3V operation. Other compatible options in the same family are the HIN206E and HIN208E, depending on the required number of drivers and receivers.
