HIN241CAZ

Overview

The HIN241CAZ is a 5V-powered RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates three receivers and three transmitters, providing full RS-232 signal conversion for single-supply operation. The device incorporates internal charge pumps to generate the necessary positive and negative voltages from a single 5V supply, eliminating the need for external dual-voltage sources. Key electrical parameters include a data rate of up to 120 kbps, output voltage levels ranging from -6V to +6V, and input thresholds compatible with standard RS-232 specifications. The component operates within a temperature range of -40°C to +85°C and is housed in an 16-pin SOIC package.

Feature Summary

• Integrates internal charge pump circuitry to derive required bipolar supply voltages from a single 5V source
• Provides complete bidirectional data conversion between TTL/CMOS logic levels and RS-232 signal standards
• Features fail-safe receiver design that defaults outputs to a high state when inputs are open or unconnected

Applications

• Industrial equipment requiring serial communication interfaces
• Modems and portable instruments utilizing RS-232 protocols
• Point-of-sale (POS) terminals and barcode scanners

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm package type and material compliance. Ensure the component meets RoHS directives if required for the target market. Cross-reference the manufacturer date code and lot traceability with authorized distributors to guarantee authenticity and storage history integrity before integration into production.

Selection Notes

Select this component when a single 5V supply is available and bipolar rails are not present. It is suitable for applications requiring moderate data rates up to 120 kbps. Consider alternative models if higher transmission speeds or lower power consumption are critical requirements for the system design.

Part Context

The HIN241 series belongs to Renesas's portfolio of interface solutions derived from legacy Intersil designs. These components are widely recognized for their reliability in establishing serial communication links in embedded systems. The CAZ variant specifically denotes the plastic small outline package configuration used in surface-mount assembly processes.

Replacement Considerations

Direct pin-compatible substitutes may include the MAX232 or SP3232 families, provided voltage levels and data rates align with system requirements. Verify functional equivalence regarding charge pump efficiency and ESD protection ratings before substitution.
