description

These identity comparators perform comparisons on two 8-bit binaryor BCD words. The SN74ALS518 provides P = Q outputs, while the´ALS520 and SN74ALS521 provide P = Q\ outputs. The SN74ALS518has an open-collector output. The SN74ALS518 and ´ALS520 feature20-k pullup resistors on the Q inputs for analog or switch data.

The SN54ALS520 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74ALS518, SN74ALS520, and SN74ALS521 are characterized foroperation from 0°C to 70°C.
