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.
