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.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1
