AM25LS2521/B2A

Comparators Overview

The AM25LS2521/B2A is an eight-bit identity comparator manufactured by Advanced Micro Devices using TTL technology. It compares two 8-bit words to determine equality, providing a high output when inputs match. The device operates on a 5 V supply voltage with a range of 4.5V to 5.5V. It features expansion capabilities and external enabling provisions. The component is housed in a 20-lead ceramic quad flatpack (CQCC20) package, suitable for military temperature ranges from -55°C to 125°C.

Comparators Feature Summary
