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

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 v ^{high–impedance circuit. For proper operation, Vin and Vout should be constrained}
to the range V_SS (V_in or V_out) V_DD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V_SS or V_DD). Unused outputs must be left open.
