HIN204CB-T

Overview

The HIN204CB-T is a dual RS-232 transceiver manufactured by Harris Corporation, designed for low-power applications. It features two drivers and two receivers with true RS-232 signal levels. The device operates from a single +5V supply and includes internal charge pumps to generate the required positive and negative voltages. It supports data rates up to 120 kbps and is housed in a compact 16-pin SOIC package.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external voltage generation components
• Single +5V power supply operation reduces system complexity and cost
• True RS-232 output voltage levels ensure compatibility with standard serial interfaces

Applications

• Portable battery-powered equipment requiring serial communication
• Industrial control systems with limited power budgets
• Modems and fax machines utilizing RS-232 standards

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that this component may be obsolete. Confirm the specific suffix 'T' indicates tape and reel packaging if required for assembly. Check for RoHS compliance status relative to the production date and ensure the 16-pin SOIC footprint matches the design constraints.

Selection Notes

Select this component when a single +5V supply is available and external inductors are undesirable due to space or cost constraints. Compare against newer CMOS alternatives like the MAX204 series for improved performance metrics. Ensure the 120 kbps speed meets the application requirements and verify the operating temperature range aligns with environmental conditions.

Part Context

This part belongs to the HIN202/HIN204 family of RS-232 transceivers. It serves as a dual-channel variant within the lineup, offering two independent drivers and receivers. The product line was designed to simplify interface design for legacy serial communications in portable devices.

Replacement Considerations

Public confirmed substitute part numbers include the MAX204CPE from Maxim Integrated and the SP204E from Exar Corporation. Verify pin-to-pin compatibility and electrical specifications before substitution.
