MOTOROLA SEMICONDUCTOR TECHNICAL DATA 4-Bit Magnitude Comparator High Performance Silicon Gate CMOS The MC74HC85 is identical in pinout and function to the LS85.
This device is similar in function to the MM74C85 and L85, but has a different pinout.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This 4 Bit Magnitude Comparator compares two 4 bit nibbles and gives a high voltage level on
