SN74ALS521DWRE4

IC COMPARATOR IDENTITY 8B 20SOIC

Manufacturer: Texas Instruments

Categories: Comparators

Quality Control: Learn More

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.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
