HD74HC283 4-bit Binary Full Adder REJ03D0607–0200 (Previous ADE-205-485) Rev.2.00 Jan 31, 2006 Description The sun (Σ) outputs are provided for each bit and the resultant carry (C4) is obtained from the fourth bit. This adder features full internal look ahead across all four bits. This provides the system designer with partial look-ahead performance at the economy and reduced package count of a ripple-carry implementation. The adder logic, including the carry, is implemented in its true for mean.

HD74HC283 4-bit Binary Full Adder REJ03D0607–0200 (Previous ADE-205-485) Rev.2.00 Jan 31, 2006 Description The sun (Σ) outputs are provided for each bit and the resultant carry (C4) is obtained from the fourth bit. This adder features full internal look ahead across all four bits. This provides the system designer with partial look-ahead performance at the economy and reduced package count of a ripple-carry implementation. The adder logic, including the carry, is implemented in its true for meaning that the end-around carry can be accomplished without the need for logic or level inversion. Features • High Speed Operation: tpd = 19 ns typ (CL = 50 pF) • High Output Current: Fanout of 10 LSTTL Loads • Wide Operating Voltage: VCC = 2 to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) • Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HC283P DILP-16 pin PRDP00.
