SN74ALS520DW Description

Short technical summary and product information.

The Texas Instruments SN74ALS520DW is an 8-bit identity comparator designed for comparing two 8-bit binary or BCD words. It operates within a voltage range of 4.5V to 5.5V and has a maximum propagation delay of 20ns at 5V and 50pF. The device features an active low output and a 20k Ohm pullup resistor on the Q input.

 

This comparator is suitable for applications requiring word comparison. It is available in a 20-SOIC package with surface mount mounting type. The operating temperature range is from 0°C to 70°C, making it suitable for commercial applications. The technology family is ALS.

 

Key electrical characteristics include a current consumption of 2.6mA minimum and 24mA maximum. The SN74ALS520DW performs P=Q\ comparisons. The package dimensions are 12.8 mm x 10.3 mm.

 

This component is ideal for digital logic systems where precise comparison of 8-bit data is required. Its surface mount capability facilitates integration into various PCB designs.
