HIN211CA-T

Overview

The HIN211CA-T is a quad line transceiver manufactured by Harris Corporation, designed for RS-232 communication applications. It integrates four drivers and five receivers within a single CMOS package. The device operates on a single 5V power supply and supports data rates up to 230 kbps. It features full-duplex transmission capability and includes internal charge pumps to generate the necessary voltages for RS-232 signaling without external components. The component is housed in a 28-pin Plastic Dual Small Outline (PDSO) or SSOP package, suitable for surface mount technology.

Feature Summary

• Integrates four independent drivers and five independent receivers for comprehensive serial communication interfaces.
• Utilizes CMOS technology to enable operation from a single 5V power supply with reduced current consumption.
• Incorporates internal charge pump circuitry to eliminate the requirement for external positive and negative voltage capacitors.

Applications

• Industrial control systems requiring robust serial data transmission.
• Modem interface circuits for data communication equipment.
• Point-of-sale (POS) terminals and peripheral connectivity.
• Computer serial port extensions and adapter designs.

Procurement Notes

Verify the manufacturer designation carefully, as the HIN211 series was originally developed by Harris Semiconductor before being acquired by Intersil and subsequently Renesas Electronics. Ensure the specific suffix 'T' corresponds to the tape-and-reel packaging format required for your assembly process. Confirm that the 'C' grade meets the commercial temperature range specifications for your intended deployment environment.

Selection Notes

Select this component when a high-density solution for multiple RS-232 channels is required within a limited board area. The integrated charge pump design simplifies layout compared to older bipolar counterparts that require external boost capacitors. Consider the 28-pin package dimensions against available PCB real estate and ensure compatibility with standard surface-mount reflow profiles.

Part Context

The HIN211 series represents a generation of low-power RS-232 transceivers that succeeded earlier bipolar designs. Originally produced by Harris Semiconductor, these devices were notable for their CMOS efficiency. Following corporate acquisitions, production rights transferred to Intersil and later Renesas Electronics, maintaining the functional lineage while updating manufacturing processes and packaging options for modern electronics.

Replacement Considerations

Direct pin-compatible replacements include the HIN211EIAZ and HIN211ECAZ variants from Renesas/Intersil. Other compatible quad transceivers such as the MAX211 or SP3232 may serve as alternatives if electrical parameters align with system requirements, though pin configurations should be verified.
