Synchronous clock enable. LVCMOS/low-voltage transistor-transistor logic
(LVTTL).
When CLK_EN = Low, Q(0:3) outputs are held low and Q(0:3)# outputs are
held high
Input clock select pin. LVCMOS/LVTTL;
When IN_SEL = Low, input IN0 is active
When IN_SEL = High, input IN1 is active
LVCMOS input clock. Active when IN_SEL = Low
No connection
LVCMOS input clock. Active when IN_SEL = High
