SN54F521J Description

Short technical summary and product information.

The SN54F521J is an 8-bit identity/magnitude comparator designed by Texas Instruments. It belongs to the F technology family, offering high-speed performance for digital comparison applications. This device compares two 8-bit words and provides outputs for identity (A equal to B) and magnitude (A greater than B or A less than B) relationships.

 

The comparator operates over a wide temperature range of -55°C to 125°C, making it suitable for military and harsh environment applications. It is available in multiple package options including CFP (W), LCCC (FK), and CDIP (J) to accommodate different assembly and thermal requirements. The F family logic ensures fast propagation delays and high drive capability.

 

Designers should consider the supply voltage and logic levels compatible with the F family. Typical applications include microprocessor systems, data processing, and digital control circuits where fast and accurate binary comparison is required. The hermetic packages provide reliability in extreme conditions.
