Pin Name
D0, /D0
Pin Function
CML/PECL/LVPECL Input (Differential). This is one of the data inputs to the
crosspoint. It will be switched either to the Q0 output, the Q1 output, both outputs, or
neither output, depending on the state of the S0 and S1 inputs.
CML/PECL/LVPECL Input (Differential). This selects input chooses which data input
switches to the Q0 output. S0 logic low selects the D0 input, while S0 logic high
selects the B input.
CML/PECL/LVPECL Input (Differential). This is the other data input to the
crosspoint. It will be switched either to the Q0 output, the Q1 output, both outputs, or
neither output, depending on the state of the S0 and S1 inputs.
Ground.
Power Supply.
CML Output (Differential). This is the other output from the crosspoint. Input S1
selects either the D0 or D1 input to be switched to this output.
CML/PECL/LVPECL Input (Differential). This select input chooses which data input
switches to the Q1 output. S1 logic low selects the D0 input, while S1 logic high
selects the D1 input.
CML Output (Differential). This is one output from the crosspoint. Input S0 selects
either the D0 or the D1 input to be switched to this output.
