SN54ALS520, SN74ALS518, SN74ALS520, SN74ALS521 8-BIT IDENTITY COMPARATORS
● Compare Two 8-Bit Words
● Choice of Totem-Pole or Open-Collector Outputs
● SN74ALS518 and ′ALS520 Have 20-kΩ Pullup Resistors on Q Inputs
● Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs TYPE INPUT PULLUP RESISTOR OUTPUT FUNCTION AND CONFIGURATION SN74ALS518 Yes P = Q open collector ′ALS520 Yes P = Q totem pole SN74ALS521‡ No P = Q totem pole ‡ SN74ALS521 is identical to ′ALS688. description These identity comparators perform comparisons on two 8-bit binary or BCD words. The SN74ALS518 has an open-collector output. The SN74ALS518 and ′ALS520 feature 20-kΩ 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.
