SN74ALS521DW TI Identity Comparator | 20-SOIC | 8-Bit, 24mA Output

Product Overview

The SN74ALS521DW is a high-performance 8-bit identity comparator from Texas Instruments, designed for fast and accurate digital comparison in advanced logic systems. Housed in a 20-pin SOIC package, this device compares two 8-bit words and provides a low-level output when they are equal. It features a totem-pole output structure capable of sinking 24 mA, making it suitable for driving bus lines and other high-capacitance loads. The SN74ALS521DW operates over a wide supply voltage range of 4.5 V to 5.5 V and is characterized for operation from 0°C to 70°C.
