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 either the A > Bout, A = Bout, or A < Bout output, leaving
the other two at a low voltage level. This device also has A > Bin, A = Bin, and
A < Bin inputs, eliminating the need for external gates when cascading.
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
