74F521PC Description

Short technical summary and product information.

The 74F521PC is an expandable 8-bit identity comparator manufactured by ON Semiconductor. This integrated circuit compares two words of up to eight bits each and provides a low output when the two words match bit for bit. The expansion input, IA=B, also functions as an active low enable input.

 

Key electrical characteristics include an operating voltage range of 4.5V to 5.5V, with a typical comparison time of 6.5 ns. The maximum propagation delay is specified at 10ns at 5V with a 50pF load capacitance. The output is active low, and the device supports current outputs of 1mA and 20mA.

 

Designed for through-hole mounting, the 74F521PC comes in a 20-PDIP package, with a standard package designation of 20-DIP (0.300", 7.62mm). The operating temperature range is from 0°C to 70°C.

 

This comparator is suitable for various digital logic applications where bit-for-bit word comparison is required. Its expandable nature allows for comparison of words longer than eight bits.
