SEMICONDUCTOR TECHNICAL DATA

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.
