SN54F521J TI Logic Comparators | 8-Bit Identity, Active Low, Military Temp

Product Overview

The SN54F521J is a high-speed 8-bit identity comparator from Texas Instruments, designed for military and aerospace applications. It compares two 8-bit binary or BCD words and provides a low-level active output when the two words are equal. The device features a fast propagation delay of typically 10 ns, making it suitable for high-performance systems. It operates over the full military temperature range of -55°C to +125°C and is available in a ceramic DIP package (J suffix). The SN54F521J is part of TI's SN54F family, known for its reliability and compatibility with TTL logic levels.
