FAST AND LS TTL DATA
4-BIT SHIFTER
(With 3-State Outputs)
The MC54/74F350 is a specialized multiplexer that accepts a 4-bit word
and shifts it 0, 1, 2 or 3 places, as determined by two Select (S0, S1) inputs.
For expansion to longer words, three linking inputs are provided for lower-or-
der bits; thus two packages can shift an 8-bit word, four packages a 16-bit
word, etc. Shifting by more than three places is accomplished by paralleling
the 3-state outputs of different packages and using the Output Enable (OE)
inputs as a third Select level. With appropriate interconnections, the F350 can
perform zero-backfill, sign-extend or end-around (barrel) shift functions.

FUNCTIONAL DESCRIPTION
The F350 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, con-
trolled 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 l–1 + S0 S1 I–2 + S0 S1 I–3
O1 = S0 S1 I1 + S0 S1 I0 + S0 S1 l–1 + S0 S1 I–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
