SN74ALS679N TI 12-Bit Address Comparator | 20-PDIP | 4.5V-5.5V, 24mA Output

Product Overview

The SN74ALS679N is a 12-bit address comparator from Texas Instruments, designed for high-performance memory and peripheral address decoding. It compares two 12-bit words (A and B) and provides a low-level active output when they are equal. The device features a 20-pin PDIP package and operates from a 4.5V to 5.5V supply. With typical propagation delays of 15ns and low power consumption, it is ideal for fast address matching in microprocessor systems.
