The D input to the adder–subtractor above would be one such control line from the control unit. The adder–subtractor above could easily be extended to include more functions. For example, a 2-to-1 multiplexer could be introduced on each B i that would switch between zero and B i ; this could be used (in conjunction with D = 1 ) to yield the ...

4-bit adder with logical block diagram shown Decimal 4-digit ripple carry adder. FA = full adder, HA = half adder. It is possible to create a logical circuit using multiple full adders to add N-bit numbers. Each full adder inputs a , which is the of the previous adder.
The serial binary subtractor operates the same as the serial binary adder, except the subtracted number is converted to its two's complement before being added. . Alternatively, the number to be subtracted is converted to its ones' complement, by inverting its bits, and the carry flip-flop is initialized to a 1 instead of to 0
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...

The full subtractor is a combinational circuit which is used to perform subtraction of three input bits: the minuend , subtrahend , and borrow in . The full subtractor generates two output bits: the difference D {\displaystyle D} and borrow out B out {\displaystyle B_{\text{out}}} .
