HIN236CB

Overview

The HIN236CB is a CMOS line transceiver manufactured by Harris Corporation, designed for RS-232 communication applications. It integrates two drivers and two receivers within a single functional unit. The device operates with a single +5V power supply and utilizes internal charge pumps to generate the necessary positive and negative voltages for EIA-232-E compliance. It is housed in a 16-pin SSOP package (SSOP16,.3) with plastic/epoxy body material. Key electrical characteristics include a maximum high-level input current of 0.00004 A and a minimum output swing of 10 V. The component supports an inverted output polarity and features Schmitt trigger input characteristics. It is rated for operation between 0 °C and 70 °C.

Feature Summary

• Integrates dual drivers and dual receivers for bidirectional RS-232 data transmission
• Utilizes internal charge pump circuitry to eliminate external capacitors for voltage generation
• Features Schmitt trigger inputs to provide noise immunity on receiver lines
• Operates from a single +5V power supply source

Applications

• Industrial control systems requiring serial communication interfaces
• Modem connections and peripheral interfacing
• Data acquisition equipment utilizing EIA-232-E standards

Procurement Notes

Verify the specific suffix 'CB' against official Harris or subsequent owner datasheets to confirm exact temperature range and package variant. Confirm RoHS compliance status as historical records indicate non-compliance for some variants. Ensure the supplier provides authentic documentation matching the 16-pin SSOP form factor. Cross-reference the manufacturer lineage if Harris assets have been acquired, as documentation may reside with the current rights holder.

Selection Notes

Select this component when a dual-driver/receiver configuration is required for RS-232 links. Verify that the system environment remains within the 0 °C to 70 °C operating range. Ensure the design accommodates the +5V supply requirement. Check that the SSOP16 footprint matches the PCB layout constraints. Confirm compatibility with EIA-232-E voltage levels before integration into the final assembly.

Part Context

The HIN236CB belongs to the HIN232 family of line transceivers produced by Harris Semiconductor. This series was widely used for implementing standard RS-232 interfaces in embedded systems. Harris Corporation's semiconductor division has undergone acquisitions, meaning current technical support or datasheet hosting may be managed by the acquiring entity. The part represents a legacy CMOS solution for serial communication.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference material. Verify pin-to-pin compatibility with modern equivalents such as the MAX232 series only after consulting current manufacturer cross-reference guides.
