HIN14C89ECBN

Overview

The HIN14C89ECBN is a high-speed RS-232 transceiver manufactured by Harris Corporation. It integrates two drivers and two receivers on a single chip, supporting data rates up to 120 kbps. The device operates from a single +5V power supply and features ECL-compatible inputs for direct interfacing with microprocessors. It includes internal charge pumps to generate the necessary positive and negative voltages for RS-232 communication without requiring external components.

Feature Summary

• Integrates dual drivers and dual receivers within a compact package
• Supports data transmission speeds up to 120 kbps
• Features ECL-compatible logic inputs for processor interface
• Includes internal charge pump circuitry for voltage generation

Applications

• Industrial control systems requiring serial communication
• Modem interface circuits
• Point-of-sale terminals
• Medical equipment serial ports

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that corporate assets may have been acquired by other entities such as Renesas Technology. Confirm the specific suffix 'CBN' corresponds to the ceramic flatpack package variant. Ensure compliance with relevant environmental standards if required for the specific application context.

Selection Notes

Select this component when a dual-channel RS-232 solution with ECL input compatibility is required. It is suitable for designs needing internal voltage generation to minimize external component count. Consider the thermal characteristics of the ceramic package if operating in high-temperature environments compared to plastic alternatives.

Part Context

This part belongs to the HIN14 series of RS-232 transceivers. The series typically offers variations in package types and pin configurations. The HIN14C89ECBN specifically denotes the dual driver/receiver configuration with ECL inputs housed in a ceramic flatpack package, distinguishing it from standard TTL-input variants.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided reference material. Verify cross-compatibility with similar dual RS-232 transceivers from other manufacturers based on pinout and electrical specifications.
