HIN209CB

Overview

The HIN209CB is a single RS-232 transmitter and receiver interface circuit manufactured by Harris Corporation. It operates from dual power supplies of +5V and +12V, distinguishing it from the single-supply variants in the HIN200-HIN213 family. The device incorporates onboard charge pump voltage converters to generate the necessary ±10V levels for RS-232 signaling. It meets EIA RS-232E and V.28 specifications, featuring true TTL/CMOS input compatibility and slew-rate-limited outputs. The receivers provide high noise rejection through hysteresis and can withstand input voltages up to ±30V.

Feature Summary

• Dual supply operation requiring both +5V and +12V inputs
• Onboard charge pump generates internal ±10V supplies
• High noise immunity with receiver hysteresis
• Compatible with standard TTL and CMOS logic levels

Applications

• Serial communication interfaces where +12V supply is available
• Industrial data transmission systems
• Equipment requiring robust RS-232 connectivity with noise resistance

Procurement Notes

Verify the specific suffix 'CB' against official Harris or Intersil datasheets to confirm temperature range and package type. Ensure the design utilizes both +5V and +12V rails, as this variant differs from the common single-supply HIN209C. Confirm pinout compatibility if replacing legacy components.

Selection Notes

Select the HIN209CB only when a +12V supply rail is present in the system architecture. For designs constrained to a single +5V source, consider alternatives like the HIN203 or HIN205 which do not require external capacitors or additional voltage rails. Evaluate board space requirements regarding the necessary external 0.1µF capacitors.

Part Context

The HIN209CB belongs to the HIN200-HIN213 family of +5V powered RS-232 transceivers. This family was designed to simplify serial interface design by eliminating the need for external voltage generators found in older standards. The HIN209 specifically offers one driver and one receiver, providing a balanced solution for basic half-duplex communication needs.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Verify electrical compatibility with Maxim MAX209 or Intersil ICL209 if cross-referencing is required.
