CC A3, B0, B1, B2, B3), three cascading inputs (A > B, A < B Low power: TTL compatibility: and A = B), and three outputs (A > B, A < B and A = B). This device compares two four-bit words (A and B) and fan out of 2 driving 74L determines whether they are “greater than,” “less than,” or Expandable to 'N' stages “equal to” each other by a high level on the appropriate out- Applicable to binary or BCD put. For words greater than four-bits, units can be cas- Low power pinout: 74L85 caded by connecting the outputs (A > B, A < B, and A = B) of the least significant stage to the cascade inputs (A > B, A < B and A = B) of the next-significant stage. In addition the least significant stage must have a high level voltage (V ) applied to the A = B input and low level voltage IN(1) (V ) applied to A > B and A < B inputs.
