Overview
MOTOROLA SEMICONDUCTOR TECHNICAL DATA 8-Bit Equality Comparator High–Performance Silicon–Gate CMOS The MC54/74HC688 is identical in pinout to the LS688.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC688 compares two 8–bit binary or BCD words and indicates whether or not they are equal.
By using the Cascade Input, two or more of the devices may be cascaded to compare words of more than 8 bits.
