100181DCQR

Overview

The 100181DCQR is a 4-bit Arithmetic Logic Unit (ALU) from the National Semiconductor 100K Series. It operates within a supply voltage range of -4.2V to -5.7V and supports an operating temperature range of 0°C to 85°C. The component is housed in a 24-CDIP package with dimensions of 0.600 inches (15.24mm). This logic device is designed for specialized arithmetic and logical operations in digital systems.

Feature Summary

• Performs arithmetic and logical functions as a dedicated ALU
• Operates on negative supply voltage rails
• Configurable gate and inverter structures

Applications

• Digital signal processing circuits
• Computer arithmetic units
• Control logic systems

Procurement Notes

Verify RoHS compliance status, as sources indicate non-compliance. Confirm package type is 24-CDIP. Check manufacturer documentation for exact pinout and electrical characteristics. Ensure compatibility with -4.2V to -5.7V power supplies. Validate operating temperature range requirements against application needs.

Selection Notes

Select this component for applications requiring a standalone 4-bit ALU with negative voltage operation. Consider the 24-CDIP package for through-hole mounting. Verify that the 0°C to 85°C temperature range meets environmental specifications. Compare performance against other 100K series devices if higher integration is needed.

Part Context

This part belongs to the National Semiconductor 100K Series of specialty logic components. It serves as a fundamental building block for arithmetic operations in legacy or specific industrial digital designs. The device provides discrete logic functionality rather than integrated microprocessor capabilities.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the 100K series. Verify functional equivalence for 4-bit ALU operations. Check voltage and temperature specifications before substitution.
