HIN207ACB

Overview

The HIN207ACB is a single-driver, triple-receiver RS-232 transceiver manufactured by Harris Corporation. It operates on a single +5V supply and utilizes onboard charge pumps to generate the required ±10V levels for RS-232 signaling. The device supports data rates up to 120 kbps and features true TTL/CMOS input compatibility. It includes slew-rate-limited outputs to minimize electromagnetic interference and receivers with hysteresis for improved noise rejection. The component meets EIA RS-232E and V.28 specifications.

Feature Summary

• Onboard voltage conversion generating ±10V from a single +5V source
• TTL/CMOS compatible inputs with slew-rate-limited drivers
• High-noise rejection receivers with input hysteresis

Applications

• Serial communication interfaces in systems lacking ±12V power supplies
• Industrial control equipment requiring robust RS-232 connectivity
• Data acquisition systems needing reliable serial transmission

Procurement Notes

Verify manufacturer lineage as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm that the specific HIN207ACB part number corresponds to the original Harris datasheet specifications rather than updated equivalents. Check for RoHS compliance status and moisture sensitivity levels before integration into production workflows.

Selection Notes

Select this component when a single-ended driver and multiple receivers are required within a standard RS-232 interface. Ensure the application environment stays within the specified operating temperature range. Verify that external capacitor values meet the minimum requirements for the onboard charge pump stability. Consider pinout compatibility if replacing legacy designs.

Part Context

The HIN207 belongs to the HIN200-HIN213 family of +5V powered RS-232 transmitters and receivers. This series was designed to simplify interface circuits by eliminating the need for dual polarity power supplies. The HIN207 specifically provides one driver and three receivers, offering flexibility for complex serial bus topologies.

Replacement Considerations

Check for direct equivalents such as the MAX207 or MAX211 from Maxim Integrated. Verify pin-to-pin compatibility and electrical parameter alignment, particularly regarding drive strength and receiver threshold voltages, before substituting.
