Pin Function

1, 2

S, /S

CML, PECL, LVPECL Input Selector: This differential CML input is one of the inputs to

the logic block. It represents either one Boolean input for a 2-variable logic function,

or the select input for a 2-input MUX.

3, 4

A, /A

CML, PECL, LVPECL Input: This is one of the differential inputs to the logic block. For

a 2-variable logic function, it is either a constant value or a Boolean input. For a 2-

input MUX, this signal represents the output when S is set to logic zero.

5

GND

Ground.

6, 7

/Q, Q

Differential CML Output: This is the differential CML output for the logic block. For

termination guidelines, see Figure 3.

8, 9

B, /B

CML, PECL, LVPECL Input: This is one of the differential inputs to the logic block. For

a 2-variable logic function, it is either a constant value or a Boolean input. For a 2-

input MUX, this signal represents the output when S is set to logic one.
