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.
Features
• 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
• These Devices are Pb−Free and are RoHS Compliant
• NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

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
high−impedance circuit. For proper operation, V
