SN74ALS521 具有集电极开路输出的 8 位标识比较器

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. The SN74ALS518 and ´ALS520 feature 20-k pullup resistors on the Q inputs for analog or switch data.

The SN54ALS520 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS518, SN74ALS520, and SN74ALS521 are characterized for operation from 0°C to 70°C
