SN54AS885 8 位幅度比较器

These advanced Schottky devices are capable of performing high-speed arithmetic or logic comparisons on two 8-bit binary or two's complement words. Two fully decoded decisions about words P and Q are externally available at two outputs. These devices are fully expandable to any number of bits without external gates. To compare words of longer lengths, the P > QOUT and P < QOUT outputs of a stage handling less significant bits can be connected to the P > QIN and P < QIN inputs of the next stage handling more significant bits. The cascading paths are implemented with only a two-gate-level delay to reduce overall comparison times for long words. Two alternative methods of cascading are shown in application information.
