Download the SN74ALS521 datasheet PDF. This datasheet also covers the SN74ALS520 variant, as both devices belong to the same 8-bit identity comparators family and are provided as variant models within a single manufacturer datasheet.
These identity comparators perform comparisons on two 8-bit binary or BCD words.
The SN74ALS518 provides P = Q outputs, while the ′ALS520 and SN74ALS521 provide P = Q outputs.
The SN74ALS518 has an open-collector output.
