|
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.
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.
