Functional Description

The 93L24 5-bit comparators use combinational circuitry to

directly generate ‘‘A greater than B’’ and ‘‘A less than B’’

outputs As evident from the logic diagram these ouptuts

are generated in only three gate delays The ‘‘A equals B’’

output is generated in one additional gate delay by decoding

the ‘‘A neither less than nor greater than B’’ condition with a

NOR gate All three outputs are activated by the active LOW

Enable Input (E)

B input permits easy expansion

The A4 and B4 inputs are the most significant inputs and

A0 B0 the least significant Thus if A4 is HIGH and B4 is

inputs except E
