DESCRIPTION

The M54/74HC283 is a high speed CMOS 4-BIT BI-

NARY FULL ADDER fabricated in silicon gate

C²MOS technology. It has the same highspeed per-

formance of LSTTL combined with true CMOS low

power consumption.

Sum (Σ) outputs are provided for each bit and a re-

sultant carry(C4) is obtained from thefourthbit. This

adderfeatures full internal look ahead across all four

bits. A 4 x n binary adder is easily built up by cas-

cading without any additional logic.

NC =

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
