Frequently Asked Questions
What is the SN74ALS679N and what does it do?
The SN74ALS679N is a 12-bit address comparator IC from Texas Instruments' ALS (Advanced Low-power Schottky) logic family. It compares two 12-bit binary words and asserts an output when they match, with an inhibit pin to disable the comparison. It supports a load capacitance of 50pF and is housed in a 20-pin DIP package.
What are the typical applications of the SN74ALS679N?
Typical applications include memory address decoding, bus arbitration, and digital logic design in embedded systems and industrial controllers. It is commonly used in systems requiring precise 12-bit address matching, such as microprocessor memory maps, programmable logic boards, and legacy TTL-based digital circuits.
What package does the SN74ALS679N come in and is it RoHS compliant?
The SN74ALS679N comes in a 20-pin Dual In-Line Package (DIP), which is ideal for through-hole PCB assembly and prototyping. Note that this part is not Pb-free (RoHS non-compliant, Pbfree Code: No), so it should be used in applications where lead-containing components are permitted.
Are there alternative parts or modern replacements for the SN74ALS679N?
Alternatives include other 12-bit address comparator ICs from the ALS or AHCT logic families. For modern designs, engineers sometimes use programmable logic devices (CPLDs/FPGAs) or dedicated bus interface ICs that offer more flexibility.
