74LV688 Datasheet (Philips) - 8-bit magnitude comparator

74LV688, 8-bit magnitude comparator

The 74LV688 is a high-speed Si-gate CMOS device, pin compatible with the 74HC/HCT688 The 74LV688 is an 8-bit magnitude comparator.

It performs comparisons of two 8-bit binary or BCD words.

The output provides P = Q (equal-to).
