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 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 74F350 can perform zero-backfill, sign-extend or endaround (barrel) shift functions.
