100182DC

Overview

The 100182DC is a 9-bit Wallace Tree Adder integrated circuit manufactured by National Semiconductor. It belongs to the 100K series of specialty logic devices and is designed for high-speed arithmetic operations using a Wallace tree architecture. The component operates within a supply voltage range of -4.2V to -5.7V and supports an operating temperature range of 0°C to 85°C. It is housed in a 24-CDIP package with through-hole mounting, suitable for integration into printed circuit boards.

Feature Summary

• Implements Wallace Tree Adder architecture for efficient binary addition
• Provides 9-bit processing capacity for specialized logic applications
• Designed for operation with negative supply voltages typical of ECL families

Applications

• High-speed digital arithmetic circuits
• Specialized logic systems requiring fast addition/subtraction
• Industrial control systems utilizing 100K series components

Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance. Confirm package type is 24-CDIP and check for active part status. Ensure supply voltage requirements match system design (-4.2V to -5.7V). Validate manufacturer origin as National Semiconductor or Texas Instruments.

Selection Notes

Select this component when a dedicated 9-bit adder is required within legacy 100K series designs. Consider the negative voltage requirement and CDIP package constraints during PCB layout. Verify thermal performance within the specified 0°C to 85°C range for the intended environment.

Part Context

This device is part of the National Semiconductor 100K series, known for emitter-coupled logic (ECL) characteristics. It serves as a specialized logic function block rather than a general-purpose gate. The 100182 variant specifically handles 9-bit addition using optimized tree structures to minimize propagation delay compared to ripple-carry alternatives.

Replacement Considerations

Check for direct pin-compatible substitutes within the 100K family. Verify electrical compatibility regarding the -4.2V to -5.7V supply range. Ensure the replacement maintains the 9-bit width and Wallace Tree architecture for equivalent performance.
