PIN DESCRIPTION
NOTES:
1. Inputs are capable of translating the following interface standards. User can select between:
2. Outputs are user selectable to drive 2.5V, 1.8V LVTTL, eHSTL, or HSTL interface levels when used with the appropriate V
3. 3 level inputs are static inputs and must be tied to V
4. Because the gate controls are asynchronous, runt pulses are possible. It is the user's responsibility to either time the gate control signals to minimize the possibility of runt
5. Pins listed as LVTTL inputs will accept 2.5V signals when RxS = HIGH or 1.8V signals when RxS = LOW or MID.

voltage for A:
Gate control for Qn outputs. When G is LOW, these outputs are enabled. When G is HIGH, these outputs are asynchronously
disabled to the level designated by GL
Specifies output disable level. If HIGH, the outputs disable HIGH. If LOW, the outputs disable LOW.
Clock outputs
Selects single-ended 2.5V LVTTL (HIGH), 1.8V LVTTL (MID) clock input or differential (LOW) clock input
Sets the drive strength of the output drivers to be 2.5V LVTTL (HIGH), 1.8V LVTTL (MID) or HSTL (LOW) compatible. Used in
