HIN206CP

Overview

The HIN206CP is a dual transmitter and receiver RS-232 interface circuit manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing onboard voltage doublers and inverters to generate the required ±10V swings for RS-232 communication. The device meets EIA RS-232E and V.28 specifications with data rates up to 230kbits/s. Key electrical parameters include ±15kV ESD protection on I/O pins, low power consumption of typically 5mA, and a shutdown current of 1µA. It features TTL/CMOS compatible inputs and outputs with 0.5V hysteresis.

Feature Summary

• Single +5V power supply operation with integrated charge pump
• High-speed ISDN compatibility supporting 230kbits/s data rates
• Robust electrostatic discharge protection rated at ±15kV
• Low power shutdown mode with active receiver wakeup capability

Applications

• RS-232 serial communication interfaces in battery-powered equipment
• ISDN terminal adapters and high-speed modem connections
• Industrial control systems requiring noise-resistant serial links

Procurement Notes

Verify the manufacturer origin carefully as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm the specific suffix 'CP' indicates commercial temperature range and ceramic package status. Request original datasheets to validate pinout and electrical characteristics against current equivalents.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 levels are required without external negative voltage generators. The HIN206CP is suitable for applications needing two receivers that remain active during shutdown for system wakeup. Ensure the design accounts for the ±15kV ESD protection requirements if exposed ports are anticipated.

Part Context

The HIN206CP belongs to the HIN2xxxE family of RS-232 transceivers designed for high-speed performance. This family was engineered to replace traditional dual-supply solutions, simplifying power management in portable and industrial electronics. The device represents a transition era in serial communication ICs before USB and Ethernet became dominant.

Replacement Considerations

Public confirmed substitutes include the MAX206CPE and the SP206ECE. These components offer similar functionality with single +5V supplies and RS-232 compliance. Verify pin-to-pin compatibility and thermal specifications before substitution.
