HIN238CB

Overview

The HIN238CB is a quad transceiver manufactured by Harris Corporation, designed for RS-232 communication applications. It features four drivers and four receivers, supporting data rates up to 120 kbps. The device operates on a single 5 V power supply and utilizes internal charge pumps to generate the necessary positive and negative voltages for RS-232 signaling without external components. It is housed in a 24-pin Plastic Dual In-line Package (PDIP) suitable for through-hole mounting. The component functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent drivers and four receivers for full RS-232 signal conversion
• Utilizes internal charge pump circuitry to eliminate the need for external capacitors
• Operates from a single 5 V power supply source

Applications

• Industrial equipment serial communication interfaces
• Computer peripheral connection modules
• Embedded systems requiring RS-232 connectivity

Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments acquired Harris Semiconductor's logic products. Ensure the part number suffix 'CB' corresponds to the specific commercial grade and package variant required for your design. Cross-reference with current TI datasheets to confirm pinout compatibility and electrical specifications before finalizing procurement.

Selection Notes

Select this component when a quad RS-232 transceiver is needed for through-hole PCB assembly. It is appropriate for designs requiring 120 kbps data rates and operation at standard 5 V logic levels. Consider alternative packages if surface-mount technology is preferred or if extended industrial temperature ranges are required beyond the commercial specification.

Part Context

This component belongs to the HIN238 series of RS-232 line transceivers originally developed by Harris Semiconductor. Following the acquisition of Harris Semiconductor by Texas Instruments, these parts are now managed under the TI portfolio. The HIN238CB represents the commercial temperature grade version packaged in a standard 24-pin PDIP format.
