MC14008B
4-Bit Full Adder
The MC14008B 4–bit full adder is constructed with MOS
P–channel and N–channel enhancement mode devices in a single
monolithic structure. This device consists of four full adders with fast
internal look–ahead carry output. It is useful in binary addition and
other arithmetic applications. The fast parallel carry output bit allows
high–speed operation when used with other adders in a system.
Look–Ahead Carry Output
Diode Protection on All Inputs
All Outputs Buffered
Supply Voltage Range = 3.0 Vdc to 18 Vdc
Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range
Pin–for–Pin Replacement for CD4008B
MAXIMUM RATINGS (Voltages Referenced to VSS) (Note 2.)

2. Maximum Ratings are those values beyond which damage to the device
may occur.
3. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
v vhigh–impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS (Vin or Vout) VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left open.
