DM74ALS521N Description

Short technical summary and product information.

The DM74ALS521N from ON Semiconductor is an 8-bit comparator that performs an "equal to" comparison of two 8-bit words. It features totem pole outputs suitable for wire-AND cascading. The device operates over a supply voltage range of 4.5V to 5.5V and has an operating temperature range of 0°C to 70°C.

 

Key electrical characteristics include a maximum propagation delay of 20ns at 5V and 50pF. The comparator has an active low output and is designed for through-hole mounting in a 20-PDIP package.

 

This component is functionally and pin-for-pin compatible with the LS family counterpart, utilizing an advanced oxide-isolated, ion-implanted Schottky TTL process. It is suitable for applications requiring precise digital word comparison.
