HIN232CB-T

Overview

The HIN232CB-T is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Harris Corporation. It meets EIA RS-232E and V.28 specifications, operating on a single +5V power supply with onboard charge pump converters generating ±10V supplies. The device features two drivers and two receivers, supporting data rates up to 230kbit/s. It utilizes a 16-pin SOICN package with dimensions of 9.9 x 3.9 mm and a 1.3mm pitch. The operational temperature range spans from 0°C to +70°C.

Feature Summary

• Onboard voltage doubler and inverter generate required ±10V supplies from a single +5V source using only 0.1µF external capacitors.
• Drivers feature true TTL/CMOS input compatibility, slew rate limiting, and 300Ω power-off source impedance.
• Receivers handle ±30V input voltages with 3kΩ to 7kΩ input impedance and 0.5V hysteresis for improved noise rejection.

Applications

• High-speed RS-232 communications ports in computer systems
• Portable, mainframe, and laptop computers
• Peripheral devices such as printers and terminals

Procurement Notes

Verify the specific suffix 'T' against official Harris or Intersil documentation to confirm tape-and-reel packaging status. Ensure the component matches the RoHS compliance requirements if applicable. Cross-reference the manufacturer history, noting that Harris Semiconductor assets were acquired by Renesas Electronics, to identify current valid part numbers and datasheets.

Selection Notes

Select this component for applications requiring high-speed RS-232 communication without access to ±12V power rails. It is suitable for space-constrained designs due to the small 0.1µF capacitor requirement. Verify that the 230kbit/s data rate and 0°C to +70°C temperature range meet the system's environmental and performance needs.

Part Context

The HIN232A series belongs to the HIN200-HIN213 family of RS-232 transmitters and receivers designed for +5V operation. This family eliminates the need for dual power supplies by integrating charge pumps. The HIN232 variant specifically provides two drivers and two receivers, making it a standard choice for basic serial communication interfaces in industrial and consumer electronics.

Replacement Considerations

Check for equivalents from Intersil or Renesas Electronics, such as the HIN232ACBNZ or HIN232CPZ, which share similar functional specifications. Verify pinout compatibility and electrical parameters before substitution.
