HIN206IB

Overview

The HIN206IB is a dual RS-232 transceiver manufactured by Harris Corporation, designed for single-supply operation. It features an internal charge pump that generates the required positive and negative voltages from a single 5V supply, eliminating the need for external dual supplies. The device complies with EIA/TIA-232 standards and includes protection circuits to withstand input voltages up to ±30V. It operates within a temperature range of -40°C to +85°C and is housed in a standard DIP-16 package.

Feature Summary

• Internal charge pump eliminates requirement for external dual voltage supplies
• Input protection against ±30V ensures robustness in noisy environments
• Single 5V power supply operation simplifies system design

Applications

• Industrial control systems requiring reliable serial communication
• Embedded systems with limited power supply options
• Data acquisition equipment interfacing with PC serial ports

Procurement Notes

Verify manufacturer authenticity as Harris Corporation assets have been acquired by Renesas Electronics. Confirm the specific suffix 'IB' denotes industrial temperature grade (-40°C to +85°C). Check current availability through authorized distributors or Renesas channels, as original Harris branding may be phased out in favor of Renesas part numbers.

Selection Notes

Select this component when a dual RS-232 interface is needed with single-supply constraints. Ensure the application requires the industrial temperature range specified by the 'IB' suffix. Compare against newer generations like the MAX3232 if lower power consumption is critical, as older designs may consume more quiescent current.

Part Context

Harris Corporation was a prominent manufacturer of semiconductors before its semiconductor division was acquired by Intersil, which was subsequently acquired by Renesas Electronics. The HIN206 series represents legacy RS-232 drivers widely used in established industrial and commercial equipment. Current support and datasheets are managed under the Renesas Electronics portfolio.

Replacement Considerations

Direct pin-compatible replacements include the MAX3232 (Maxim Integrated) and the SP3232 (Exar/Renesas). Verify that the replacement supports the same 5V supply and meets the required signal integrity specifications for the specific application environment.
