The binary sum appears on the Sum S 0 S 3 and outgoing carry C 4 outputs. The binary weight of the various inputs and outputs is indicated by the subscript numbers, representing powers of two.
Due to the symmetry of the binary add function, the 74F can be used either with all inputs and outputs active HIGH positive logic or with all inputs and outputs active LOW negative logic.

Due to pin limitatio, the intermediate carries of the 74F are not brought out for use as inputs or outputs. However, other mea can be used to effectively iert a carry into, or bring a carry out from, an intermediate stage.
Figure 2 shows how to make a 3-bit adder.
Tying the operand inputs of the fourth adder A 3, B 3 LOW makes S 3 dependent only on, and equal to, the carry from the third adder. Using somewhat the same principle, Figure 3 shows a way of dividing the 74F into a 2-bit and a 1-bit adder. The third stage adder A 2, B 2, S 2 is used merely as a mea of getting a carry C 10 signal into the fourth stage via A 2 and B 2 and bringing out the carry from the second stage on S 2.
Similarly, when A 2 and B 2 are the same the carry into the third stage does not influence the carry out of the third stage. Figure 4 shows a method of implementing a 5-input encoder, where the inputs are equally weighted. The outputs S 0, S 1 and S 2 present a binary number equal to the number of inputs I 1 I 5 that are true. Figure 5 shows one method of implementing a 5-input majority gate.
When three or more of the inputs I 1 I 5 are true, the output M 5 is true. Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditio is not implied. Either voltage limit or current limit is sufficient to protect inputs. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and c whose failure to perform when properly used in accordance with itructio for use provided in the labeling, can be reasonably expected to result in a significant injury to the user A critical component in any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.
