74F521PC Description

Short technical summary and product information.

The 74F521PC from Texas Instruments is an expandable 8-bit identity comparator. It compares two 8-bit words and outputs a low signal when the words match bit for bit. The device features an active low enable input that also serves as an expansion input.

 

Key electrical specifications include a supply voltage range of 4.5V to 5.5V and an operating temperature range of 0°C to 70°C. The maximum propagation delay is 10ns at 5V and 50pF. It supports 8-bit word comparisons and is expandable to any word length.

 

This comparator is available in a 20-pin PDIP package suitable for through-hole mounting. The output is active low, indicating identity when the input words match. The 74F521PC is part of the 74F series logic family.

 

Applications for the 74F521PC include data comparison, word matching, and error detection in digital systems. Its expandable nature allows for flexible implementation in systems requiring comparison of longer data words.
