SN74LS353 Overview
DUAL 4-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS The LSTTL/ MSI SN54/ 74LS353 is a Dual 4-Input Multiplexer with 3-state outputs. It can select two bits of data from four sources using mon select inputs. The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (E0) inputs, allowing the outputs to interface directly with bus oriented systems.
