Features  
Description  
• Buffered Inputs and Outputs  
The CD74HC85 and CD74HCT85 are high speed  
magnitude comparators that use silicon-gate CMOS  
technology to achieve operating speeds similar to LSTTL  
with the low power consumption of standard CMOS  
integrated circuits.

• Serial or Parallel Expansion Without External Gating  
These 4-bit devices compare two binary, BCD, or other  
monotonic codes and present the three possible magnitude  
results at the outputs (A > B, A < B, and A = B). The 4-bit  
input words are weighted (A0 to A3 and B0 to B3), where A3
