Overview

HD74HC283 4-bit Binary Full Adder Description The sun ( ) 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 endaround 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 Inpu...
