HIN235CP

Overview

The HIN235CP 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 pumps generating ±10V supplies. The device features five drivers and five receivers, supporting data rates up to 120 kbps. It utilizes a 24-pin PDIP package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Onboard voltage conversion eliminates the need for external ±12V supplies
• Provides five driver and receiver channels for complex serial communication
• Includes hysteresis in receivers to enhance noise rejection capabilities

Applications

• Systems requiring multi-channel RS-232 communications ports
• Portable computers and laptop peripheral interfaces
• Industrial instrumentation and terminal connections

Procurement Notes

Verify the manufacturer designation as Harris Corporation or Intersil, noting corporate acquisitions may affect labeling. Confirm the specific suffix 'CP' corresponds to the PDIP package and commercial temperature grade. Ensure RoHS compliance status matches current production requirements.

Selection Notes

Select this component when five independent transmit and receive lines are required. It is suitable for designs constrained to a single +5V supply rail. Consider the 24-pin PDIP footprint for through-hole assembly needs. Verify that the 120 kbps speed meets system timing requirements.

Part Context

This part belongs to the HIN200-HIN213 family of RS-232 transceivers. These devices were designed to simplify interface design by integrating charge pumps. The family offers various driver/receiver combinations to accommodate different application complexity levels.

Replacement Considerations

Check for equivalents such as the HIN235CN or HIN235ACBNZ. Verify pin compatibility and electrical parameters before substitution. Note that suffixes may indicate package type or temperature range variations.
