Texas Instruments SN74ALS521DWRE4 is an 8-bit identity comparator from the 74ALS series. This device facilitates direct comparison of two 8-bit words, outputting an active low signal when both words are identical (A=B). Designed for surface mount applications on a 20-SOIC package, it operates within a supply voltage range of 4.5V to 5.5V. The component exhibits a maximum propagation delay of 20ns at 5V with a 50pF load capacitance and supports output currents of 2.6mA (high) and 24mA (low). This comparator finds application in various industrial control systems, data routing, and logic design where precise bit-wise equality detection is critical. The device is supplied in Tape & Reel packaging.
