93S62DM

Overview

The 93S62DM is a 12-bit parity generator and checker integrated circuit manufactured by National Semiconductor. It operates within a standard logic family designed for error detection in digital data transmission systems. The device provides comprehensive parity checking capabilities for 12-bit data words, ensuring data integrity through hardware-based validation. This component is housed in a 14-pin CDIP package, suitable for through-hole mounting on printed circuit boards. It functions as a dedicated logic circuit for generating and verifying parity bits, supporting reliable communication protocols in industrial and computing applications.

Feature Summary

• Performs simultaneous generation and checking of parity for 12-bit data inputs
• Provides hardware-based error detection to ensure data integrity in digital systems
• Housed in a durable 14-lead ceramic dual in-line package for robust mounting

Applications

• Digital data transmission systems requiring error detection
• Memory subsystems for parity verification
• Industrial control interfaces needing data integrity checks

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor's logic assets were acquired by Texas Instruments. Confirm the specific suffix 'DM' indicates the correct 14-CDIP package variant. Ensure compatibility with existing board layouts designed for this footprint. Check current product status as active or obsolete depending on the supply chain source. Validate that the component meets the required logic voltage levels for your specific application environment.

Selection Notes

Select this component when a dedicated 12-bit parity solution is required for legacy or specific industrial designs. Consider the physical package constraints of the 14-CDIP form factor during PCB layout. Evaluate if the fixed 12-bit width aligns with your data bus architecture. Compare against alternative logic families if modern surface-mount solutions are preferred for new designs. Ensure the operating temperature range matches your system's environmental requirements.

Part Context

This part belongs to the National Semiconductor logic catalog, specifically within the parity generator and checker category. These components were widely used before the consolidation of semiconductor assets under Texas Instruments. The 93S series represents a standard line of parity circuits designed for reliability in critical data paths. Understanding this lineage helps in sourcing replacements or understanding datasheet documentation from either National or TI archives.

Replacement Considerations

Check for direct pin-compatible substitutes such as the 93S62FM or 93S62PC if available from authorized distributors. Verify electrical specifications match exactly, particularly output drive currents and input thresholds. Consider the transition from National Semiconductor branding to Texas Instruments for future procurement consistency.
