The MC100LVEL59 is a triple 2:1 multiplexer with differential outputs. The MC100EL59 is pin and functionally equivalent to the MC100LVEL59 but is specified for operation at the standard 100E ECL voltage supply. The output data of the muxes can be controlled individually via the select inputs or as a group via the common select input. The flexibile selection scheme makes the device useful for both data path and random logic applications.
