HIN236ECA

Overview

The HIN236ECA is a high-speed RS-232 transceiver manufactured by Harris Corporation. It integrates two drivers and two receivers on a single CMOS chip, designed for EIA/TIA-232-F and V.28/V.24 communication standards. The device operates from a single +5V supply and features low quiescent current consumption. It utilizes a 16-pin SSOP package suitable for surface-mount applications. The component supports data rates up to 120 kbps with guaranteed output voltages of ±5V. It includes internal charge pumps to generate the required positive and negative supply voltages from the single +5V source.

Feature Summary

• Integrates dual drivers and dual receivers in a compact CMOS design
• Operates from a single +5V power supply without external components
• Supports standard RS-232 voltage levels with internal charge pumps
• Compatible with EIA/TIA-232-F interface specifications

Applications

• Industrial control systems requiring serial communication
• Modem interfaces in embedded devices
• Point-of-sale terminals and barcode scanners
• Computer peripheral connections

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities, noting that Harris Semiconductor assets were acquired by Renesas Electronics. Confirm the specific suffix 'ECA' corresponds to the correct temperature range and packaging variant. Request the official datasheet to validate pinout compatibility and electrical characteristics against current replacement components. Ensure RoHS compliance status is documented if required for the target assembly process.

Selection Notes

Select this component when a dual-channel RS-232 solution is needed with low power consumption and single-supply operation. Compare input threshold voltages and output drive capabilities against system requirements. Consider the SSOP package size constraints during PCB layout. Verify that the operating temperature range meets the environmental conditions of the final application. Check for availability of equivalent modern replacements if the original part is discontinued.

Part Context

The HIN236ECA belongs to the HIN232 family of RS-232 transceivers developed by Harris Semiconductor. This series was widely used in personal computers and industrial equipment before the company's semiconductor division was acquired. The device represents a transition period in CMOS RS-232 technology, offering improved performance over older bipolar implementations while maintaining compatibility with legacy standards.

Replacement Considerations

Renesas Electronics acquired Harris Semiconductor's analog product line. Equivalent parts include the RH1L232CA or other Renesas RS-232 transceivers with similar pinouts and electrical specifications. Verify functional compatibility before substitution.
