FACT DATA
FUNCTIONAL DESCRIPTION
The MC74AC350/74ACT350 is operationally equivalent to
a 4-input multiplexer with the inputs connected so that the
select code causes successive one-bit shifts of the data word.
This internal connection makes it possible to perform shifts of
0, 1, 2 or 3 places on words of any length.
A 7-bit data word is introduced at the In inputs and is shifted
according to the code applied to the select inputs S0, S1.
Outputs O0–O3 are 3-state, controlled by an active-LOW
output enable (OE). When OE is LOW, data outputs will follow
selected data inputs; when HIGH, the data outputs will be
forced to the high-impedance state. This feature allows
shifters to be cascaded on the same output lines or to a
common bus. The shift function can be logical, with zeros
pulled in at either or both ends of the shifting field; arithmetic,
where the sign bit is repeated during a shift down; or end
around, where the data word forms a continuous loop.
LOGIC EQUATIONS
O0=S0 S1 I0+S0 S1 I–1+S0 S1 I–2+S0 S1 I–3
O1=S0 S1 I1+S0 S1 I0+S0 S1 I–1+S0 S1 II–2
O2=S0 S1 I2+S0 S1 I1+S0 S1 I0+S0 S1 I–1
O3=S0 S1 I3+S0 S1 I2+S0 S1 I1+S0 S1 I0
