HIN207ECA

Overview

The HIN207ECA 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 offers high noise rejection through receiver hysteresis. The component is housed in an SOIC-24 package and is designed for applications where dual voltage supplies are unavailable.

Feature Summary

• Onboard voltage conversion eliminates the need for external ±12V power supplies
• High noise immunity provided by receiver hysteresis and ±30V input tolerance
• Slew-rate-limited drivers reduce signal reflections and EMI

Applications

• Industrial serial communication interfaces
• Data acquisition systems requiring RS-232 connectivity
• Embedded control units with limited power supply options

Procurement Notes

Verify manufacturer authenticity as Harris Corporation's semiconductor assets were acquired by Intersil, which was subsequently acquired by Renesas Electronics. Ensure the specific suffix matches the required package and temperature grade. Request original datasheets or official change notifications to confirm current production status and compliance details before procurement.

Selection Notes

Select this component when a single +5V supply is available but RS-232 signaling is required. It is suitable for designs needing one transmitter and three receivers. Compare against the HIN207ECBZ-T for equivalent functionality if sourcing from current manufacturers like Renesas. Verify that the 120 kbps speed meets system requirements.

Part Context

This part belongs to the HIN200-HIN213 family of +5V powered RS-232 transmitters and receivers. These devices were originally designed by Harris Semiconductor to simplify interface design by integrating charge pumps. The family allows designers to replace traditional dual-supply solutions with single-supply components, reducing board space and complexity in legacy and industrial electronics.

Replacement Considerations

The HIN207ECBZ-T is a direct functional equivalent currently produced by Renesas Electronics following the acquisition of Intersil and Harris Semiconductor assets. Verify pinout compatibility and electrical specifications against the original Harris datasheet to ensure seamless integration.
