PIN AND FUNCTION COMPATIBLE WITH 54/74LS283
The M54/74HC283is a high speed CMOS 4-BIT BI-NARY FULL ADDER fabricated in silicon gate
C 2
MOS technology.It has the same high speed 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 the fourth bit.This adder features full internal look ahead across all four bits.A 4x n binary adder is easily built up by cas-cading without any additional logic.
All inputs are equipp ed with protection circuits against static discharge and transient excess volt-age.
