74F350
4-Bit Shifter with 3-STATE Outputs
General Description
The 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-order bits; thus two
packages can shift an 8-bit word, four packages a 16-bit
word, etc. Shifting by more than three places is accom-
plished 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
74F350 can perform zero-backfill, sign-extend or end-
around (barrel) shift functions.
