HIN233ECB

Overview

The HIN233ECB is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Harris Corporation. It meets EIA-232E and V.28 specifications, requiring only a single +5V power supply with onboard charge pump voltage converters generating ±10V supplies. The device features two drivers and two receivers in a 16-pin SOIC package. Key electrical parameters include a data rate of 230 kbit/s, typical power consumption of 5 mA, and an operating temperature range of 0°C to +70°C. It utilizes 0.1 µF external capacitors for the charge pump.

Feature Summary

• Onboard voltage doubler and inverter generate required ±10V supplies from a single +5V source
• High data rate capability up to 230 kbit/s for fast communication
• TTL/CMOS compatible inputs with true logic level translation
• Low power consumption design suitable for battery-operated systems

Applications

• Portable computers and laptop serial ports
• Mainframe computer peripheral connections
• Printers and terminals requiring RS-232 interfaces
• Instrumentation and UPS systems
• Modem applications

Procurement Notes

Verify the specific suffix 'CB' against official Harris or Intersil datasheets to confirm pinout and package dimensions. Ensure compatibility with existing PCB footprints. Confirm RoHS compliance status if required for your assembly process. Check for active production status as older Harris components may have limited availability.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are not. It is suitable for applications requiring 2 drivers and 2 receivers. Compare against similar parts like HIN232 if fewer channels are needed. Verify that the 230 kbit/s speed meets system requirements. Ensure the SOIC-16 package fits the design constraints.

Part Context

The HIN233 series belongs to Harris Corporation's family of high-speed RS-232 transceivers. These devices were designed to simplify interface design by eliminating the need for dual voltage supplies. The HIN233 specifically provides two driver and two receiver channels, offering more connectivity than the single-channel HIN232 within the same low-power architecture.

Replacement Considerations

Check for direct equivalents such as the MAX233 or SP233 which offer similar functionality. Verify pin-to-pin compatibility before substitution. Ensure the replacement part supports the same 230 kbit/s data rate and operates within the 0°C to +70°C temperature range.
