MM54C85 MM74C85 4-Bit Magnitude Comparator
General Description
The MM54C85 MM74C85 is a four-bit magnitude compara-
tor which will perform comparison of straight binary or BCD
codes The circuit consists of eight comparing inputs (A0
A1 A2 A3 B0 B1 B2 B3) three cascading inputs (A l B
A k B and A e B) and three outputs (A l B A k B and
A e B) This device compares two four-bit words (A and B)
and determines whether they are ‘‘greater than ’’ ‘‘less
than ’’ or ‘‘equal to’’ each other by a high level on the appro-
priate output For words greater than four-bits units can be
cascaded by connecting the outputs (A l B A k B and
A e B) of the least significant stage to the cascade inputs
(A l B A k B and A e B) of the next-significant stage In
addition the least significant stage must have a high level
voltage (VIN(1)) applied to the A e B input and low level
voltage (VIN(0)) applied to A l B and A k B inputs
