HIN207EIBZ

Overview

The HIN207EIBZ is a high-speed RS-232 transceiver manufactured by Intersil, designed for single-supply +5V operation. It integrates onboard charge pump voltage converters to generate the necessary positive and negative supplies from a single 5V source, eliminating the need for external ±12V rails. The device features one driver and three receivers, supporting data rates up to 230 kb/s. It operates within a supply voltage range of 4.75 V to 5.25 V and consumes approximately 20 mA of operating current. The component provides robust ±15 kV ESD protection on I/O pins and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates onboard charge pump circuitry to generate internal voltage levels from a single +5V supply
• Provides ±15 kV electrostatic discharge (ESD) protection on transmitter outputs and receiver inputs
• Features true TTL/CMOS input compatibility with slew-rate-limited outputs to minimize electromagnetic interference

Applications

• ISDN terminal adaptors requiring high-speed serial communication
• Portable computer systems including laptops and mainframes
• Peripheral interfaces such as printers and terminals
• Instrumentation and UPS systems needing reliable RS-232 connectivity

Procurement Notes

Verify the specific suffix 'IBZ' against the manufacturer's datasheet to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as this component may be subject to end-of-life restrictions or limited stock conditions. Ensure the ordering quantity meets distributor minimums if applicable.

Selection Notes

Select the HIN207EIBZ when a design requires one transmit channel and three receive channels in a single IC. This part is suitable for applications where space constraints prevent the use of discrete charge pump components. Verify that the system environment falls within the -40°C to +85°C operating range and that the 5V logic levels are compatible with the connected microcontroller or processor.

Part Context

The HIN207EIBZ belongs to the HIN20xE family of RS-232 transceivers from Intersil. This family shares common architectural features such as single-supply operation and high ESD protection. Variations within the family, such as the HIN206E or HIN208E, differ primarily in the number of drivers and receivers provided, allowing designers to choose the configuration that best matches their pin count and interface requirements.

Replacement Considerations

Direct functional substitutes within the same family include the HIN207ECBZ for commercial temperature ranges. Other compatible devices from different manufacturers must be verified for pin-to-pin compatibility, identical driver/receiver counts, and matching electrical specifications regarding data rate and ESD protection levels.
