MC74ACT350 - 4-BIT SHIFTER WITH 3-STATE OUTPUTS

General 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.

Key Features

  • 7 3-8 Unit Fig. No.
  • Voltage Range 5.0 V is 5.0 V ±0.5 V.

MC74AC350 MC74ACT350 4ĆBit Shifter With 3ĆState Outputs The MC74AC350/74ACT350 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 ′AC/ACT350 can perform zero-backfill, sign-extend or end-around (barrel) shift functions.
