HIN233ACP

Overview

The HIN233ACP is a high-speed RS-232 transceiver manufactured by Harris Corporation. It operates from a single +5V power supply and integrates onboard charge pump voltage converters to generate the required positive and negative voltages for RS-232 signaling, eliminating the need for external dual supplies. The device features two drivers and two receivers, supporting data rates up to 230 kbit/s. It meets EIA-232-E and V.28 specifications. The component utilizes a 16-pin SSOP package and is designed for low power consumption with typical supply current of 5mA.

Feature Summary

• Integrates onboard charge pump voltage converters to generate necessary supply rails from a single +5V source
• Provides true TTL/CMOS input compatibility for drivers and robust noise rejection in receivers via hysteresis
• Features 300Ω power-off source impedance on outputs to prevent bus contention during system power-down

Applications

• High-speed RS-232 communications ports in computer systems
• Portable, mainframe, and laptop computers requiring serial connectivity
• Peripheral devices such as printers and terminals
• Instrumentation and Uninterruptible Power Supply (UPS) systems
• Modem applications

Procurement Notes

Verify the manufacturer status carefully, as Harris Semiconductor assets were acquired by Renesas Electronics. Confirm whether the specific HIN233ACP part number represents original Harris stock or a Renesas continuation. Check for RoHS compliance markings if environmental regulations apply to your deployment, noting that older Harris parts may not be compliant.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are required. It is suitable for designs needing moderate data rates up to 230 kbit/s. Ensure the 16-pin SSOP package fits the PCB layout constraints. Consider alternatives if higher data rates or lower power consumption are critical requirements for the target application.

Part Context

The HIN233ACP belongs to the HIN232/HIN233 family of high-speed RS-232 transceivers. This series was widely used in legacy computing and industrial equipment before the prevalence of USB and Ethernet interfaces. The 'Harris' branding indicates pre-acquisition manufacturing, which may affect long-term availability and support channels compared to modern equivalents.

Replacement Considerations

Renesas Electronics acquired Harris Semiconductor's analog and mixed-signal product lines. Verify if Renesas offers direct pin-compatible replacements or updated versions of the HIN233 series. Check datasheet revisions to ensure functional equivalence regarding electrical characteristics and pinout definitions.
