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. http://onsemi.com 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 This Device is Pb−Free and is RoHS Compliant MAXIMUM RATINGS (Voltages Referenced to VSS) Parameter Value Unit −0.5 to +18.0 V −0.5 to VDD + 0.5 V Input or Output Current (DC or Transient) per Pin ±10 mA PD Power Dissipation, per Package (Note 1) 500 mW TA Ambient Temperature Range −55 to +125 °C Tstg Storage Temperature Range −65 to +150 °C TL Lead Temperature (8−Second Soldering) 260 °C Symbol VDD Vin, Vout Iin, Iout DC Supply Voltage Range Input or Output Voltage Range (DC or Transient) 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, 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.
